  • How to sort Associated non-metallic fluorite How to sort Associated non-metallic fluorite Dec 29, 2022
    How to sort Associated non-metallic fluorite   According to the different components of fluorite ore associated minerals, fluorite can generally be divided into monotypic fluorite, quartz-type fluorite, sulfide-type fluorite, calcite-type fluorite, barite fluorite, silica-type fluorite, carbonate-type fluorite, etc. As an important non-metallic mineral raw material, fluorite is widely used in chemical, steel, aluminum, ceramics and other industries, and is the main raw material for the preparation of fluorine, with the development of science and technology, fluorite in With the development of science and technology, the use of fluorspar in high-tech industries has gradually increased and become an important strategic mineral resource. Then how to effectively improve the taste of fluorspar is vital to the utilization of fluorspar.     So how to effectively improve the taste of fluorspar ore, Hefei Mingde photoelectricity recommended the use of artificial intelligence sorting machine. For the situation of associated fluorite ore, ordinary ore color sorter has been unable to complete the fluorite color separation, because the traditional photoelectric color sorter can only rely on a simple color difference for selection, the more obvious the color difference the better the sorting effect, the logic of a single criterion. Mingde photoelectric launch artificial intelligence sorting machine is the use of AI deep convolutional neural network (CNN) and other artificial intelligence means of material image analysis and processing technology, AI photoelectric sorting technology can automatically extract the multi-dimensional characteristics of the material, such as texture, shape, color, texture, luster, etc., greatly enhance the sorting effect, expand the sorting scene and material types, to meet the market diversification and personalized sorting requirements.

  • In winter, what should be paid attention to the ore color separator? In winter, what should be paid attention to the ore color separator? Dec 29, 2022
    In winter, what should be paid attention to the ore color separator?   Mingde photoelectric ore color sorter is divided into quartzite color sorter, potassium feldspar color sorter, talc color sorter, fluorite color sorter, wollastonite color sorter, calcium carbonate, barite and other non-metallic ore color sorter and metal ore color sorter according to the different needs of ore sorting. 2021 is affected by La Nina, it may be a cold winter. For the use of ore color sorter in winter, Mingde photoelectric gives the following small suggestions.      1, ore color sorter winter use tips. Each shift should open the ore color sorter for preheating half an hour before work, the working environment should be kept above +5℃, especially in the northern region must pay attention to the working environment. (1) In the cold winter, the ball valve should be opened slowly to prevent the high-speed airflow from freezing the pipe. (2) After each shift, the residual gas and water in each equipment should be emptied strictly to prevent the phenomenon of icing.     2、 How to judge whether there is blockage in the gas supply pipe, Mingde photoelectric tips.  Ore color sorter in the working process, the air compressor again when starting, need to pay attention to the color sorter side air inlet pressure table and the air compressor indicates the same air pressure value. If lower than the value of the compressor pressure table, that indicates that the pipeline is blocked (dirty plug or ice plug), please clean the pipeline and each filter element.    
  • Factors affecting the sorting effect of ore color sorter Factors affecting the sorting effect of ore color sorter Jan 03, 2023
    Factors affecting the sorting effect of ore color sorter For the ore color sorter, I believe most mining enterprises have long been familiar with. So, ore color sorter in the process of widely used in the mining industry sorting work, whether it can meet the needs of all customers, its sorting effect by which factors determine or influence it, Mingde photoelectric after a long-term use of our ore color sorter customer analysis, for different materials, different enterprises, we summarized some of the content.       We often say, ore color sorter is a new automatic equipment, some people say ore color sorter is a kind of "robot", usually, ore color sorter mainly by the feeding system, photoelectric system, control system and sorting system four system composition. As a kind of ore sorting automation equipment, and weigh the four systems and judge the value of its work or mainly depends on the ore color sorter color sorting accuracy, processing capacity, raw materials containing impurities, selection of net rate and other factors.   In the actual production process, these factors are one, there are mutual influence and constraints of the relationship, must be examined at the same time. Our company (Mingde photoelectric) developed a new ore color sorter, in the software upgrade and spray valve response speed to meet the case at the same time, the servo system movement speed, the highest speed of the conveyor belt and the purity of raw materials will affect the color separation accuracy and the size of the processing capacity per unit of time; In addition, some manufacturers in the actual sorting process, the bad material cycle sorting, greatly reducing the rate of finished ore, in the effective time The efficiency of the qualified products is reduced within the effective time, which leads to the increase of the take-out ratio. If the take-out ratio is set too high, it will affect the selection rate and processing capacity of these two indicators; if set too low, the selected waste contains too much normal material, will cause waste. In a comprehensive manner, improve the sensitivity, the better the color separation effect, the greater the belt-out ratio; and the output requirements are also a direct impact on the color separation effect and belt-out ratio. Therefore, after analysis, we have increased the track speed of the color sorter. Compared with other manufacturers, our crawler speed is several times of the same industry manufacturers. They want to improve the output, in can not solve the track speed problem, can only increase the material coverage, in the field production, such coverage will seriously reduce the effective distance between the materials, in the sorting will reduce the resolution, resulting in a lot of bad material "escape", therefore, such a way will only make the material to increase the take-out ratio, and further reduce the separation rate. More reduce the net selection rate. In the long run, for our mining manufacturers, simply can not meet the production requirements, let alone recover costs and increase efficiency.       If you can not achieve the expected color separation effect, in addition to improper debugging, there is a little influence is the rate of raw material impurities. Low rate of impurities, impurities between the interval is large, leaving the servo system response time is long, you can also increase the speed of the conveyor belt to improve production. Similarly, the higher the initial purity of the raw material, the less impurities, the higher the accuracy of color selection, the higher the accuracy, the higher the yield. The normal materials and defective materials in the raw materials must exist a certain color difference; the smaller the color difference, the more difficult the color separation, the worse the performance index, the election rate of materials of different colors is also different.     The factor that has the greatest impact on the quality is the problem of color separation accuracy, we know that the high requirements for the finished material is generally to achieve high precision color separation. For example, we take quartz sand as an example, if it is used to make quartz plates, it can not be sloppy, quartz sand for quartz plates must be high purity, quartz sand can not have a little yellow skin on the surface, the hardness of the stone should also be good, so that the quartz plates made to meet the standards of the industry. In addition, high-end quartz used for export, manufacturing wafers, aerospace business, etc. requires even higher quality products. Conversely, quartz used as a filler in general glass, paint, rubber, plastic, etc. is not as demanding. A certain doping rate does not affect the application, so the yield can be pursued appropriately.       Color sorter as a typical optical-electro-mechanical integration system, involving optical-electro-mechanical soft innovation and application in various fields, the speed of upgrading is very fast, is a typical innovative technology products, mining enterprises in the use of caution, to do a full understanding of the color sorter manufacturers, the color sorter operation of in-depth understanding, so that it plays a due investment benefits.
  • How to choose ore color separator manufacturers for mining companies How to choose ore color separator manufacturers for mining companies Jan 05, 2023
    How to choose ore color separator manufacturers for mining companies In order to improve the production efficiency  , to achieve satisfactory production results, the choice of good  equipment is very necessary, then, for the ore industry, how to choose a good ore sorting equipment?   Different places of ore, because of its ore grade, mineral structure, mineral form, mineral fugacity, and particle size and other ore properties are different beneficiation process and technical conditions are different, so the beneficiation technology can not simply apply others, but must use their own ore beneficiation test to determine whether the mineral has the value of use. Therefore, for such cases, we generally recommend that ore manufacturers bring materials or mail materials to equipment manufacturers to test whether the other party's equipment to meet their own ore products. Then visit the factory on site, listen to the technical characteristics of the manufacturer's analysis of the equipment, visit the long-term use of customers.     Stone production equipment selection should be the characteristics of the ore raw materials to determine the type of equipment, from the test or other engineering experience to obtain the index value for the calculation of the process flow, to determine the quality requirements of the combination of equipment form and configuration, to determine the production capacity of the equipment model and quantity.     In the selection of equipment priority is given to equipment that is easy to operate, reliable in operation, low energy consumption and operation and management costs, at the same time, the load factor of the equipment, the particle size of the product to be processed, the amount of variation in the grading is also an important selection factor.   On the issue of quality, we must consider the manufacturer of the production equipment, to see whether the manufacturer is a formal company, whether the strength is strong, whether the reputation is trustworthy, it is recommended that it is best to personally visit the site to see if it meets their required standards. At present, the main ore equipment is ore color separator, flotation machine, magnetic separator, etc.. Among them, ore color separator has now played a vital role in the market, and its application is increasingly widespread.       Ore color separator, the lucky star of the rise of China's mining industry. Ore color separator is the use of photoelectric principle through the color distinction of the raw ore sorting large mining technology equipment, its application not only solves the lack of operator technology and quality problems, but also greatly improve the yield of ore, thereby reducing the cost of ore, can be said to the above problem is solved.     In short, the introduction of ore color separator and the continuous development of mining production technology is quite important for the development of Chinese ore. It can not only solve the dilemma of domestic ore, but also open up a new chapter of rapid development of Chinese mining industry. Make domestic ore for imported ore to produce a strong impact, get rid of its dependence, and really achieve a new revolution of domestic ore, out of China, to the world! In this regard, ore color separator should not spare pressure, continue to develop and produce more possibilities in the field, fully support the development of domestic ore, and become the booster of a new chapter in the development of China's mining industry.

  • Mineral Removal Robot Coal mine belt conveyor sorting robot material identification and positioning system Mineral Removal Robot Coal mine belt conveyor sorting robot material identification and positioning system Jan 14, 2023
    Coal mine belt conveyor sorting robot foreign object identification and positioning system As an important equipment for coal mine production, the safe operation of coal mine belt conveyor is an important foundation to ensure the normal production of coal mine. However, in the process of coal production and transportation, coal mine conveyor belts can be affected by foreign objects mined out by comprehensive mining or comprehensive excavation, etc., which can lead to serious accidents such as torn belt and broken belt. Traditional foreign object detection methods such as manual detection, radar detection and metal detectors are inefficient, costly, difficult to deploy and maintain, and have safety hazards. With the continuous development of machine vision technology, domestic and foreign institutions and scholars have conducted a lot of research on the application of machine vision technology in coal mine belt conveyor condition monitoring and target detection. Although machine vision has a certain theoretical basis in coal mine belt conveyor target detection and identification, the current coal mine belt conveyor sorting robot target identification is mainly for gangue identification, and there is less research on foreign object target identification that causes belt penetration, tearing, etc., and there is less research on precise positioning of target foreign objects.   Hereby, MingDe designed a coal mine belt conveyor sorting robot foreign object identification and positioning system, which can identify and locate different types and shapes of foreign objects on the conveyor belt.   Through a multi angle, multi-dimensional stereo high-precision camera, the intelligent robot sorter quickly scans the ore on the conveyor belt.

  • How to sort feldspar Jan 14, 2023
    How to sort feldspar Feldspar is a group of minerals consisting of aluminosilicates of potassium, sodium, calcium and barium. The main chemical composition is SiO2, Al2O3, CaO, K2O, Na2O.   Feldspar group minerals are the most important rock-forming minerals in nature, accounting for about 50%~60~ of the mineral composition of the earth's crust. Felsic minerals are widely produced in various genetic types of rocks, and are the main rock-forming minerals of magmatic and metamorphic rocks.     As feldspar is a rock-forming mineral, it is difficult to separate from other minerals in most cases, so the only feldspar deposits of industrial significance are pegmatite deposits with huge crystals that are easy to separate. I. Types of feldspar According to its chemical composition and crystallization characteristics, it can be divided into two subgroups: potassium sodium feldspar and plagioclase feldspar subgroup.   (1) Potassium-sodium feldspar subgroup   It is composed of potassium feldspar molecules and sodium feldspar molecules. The natural output of potassium feldspar are mixed with sodium feldspar, so often called potassium feldspar, all belong to potassium sodium feldspar, common potassium sodium feldspar species.   Turbidite, (K, Na)[AlSi3O8], contains sodium feldspar   molecules up to 50%, K: Na = 1: 1   Orthoclase, (K, Na)[AlSi3O8], containing sodium feldspar   molecules up to 30%, K:Na = 2:1   Microplagioclase, (K, Na)[AlSi3O8], containing sodium feldspar    molecules up to 20%, K: Na = 4: 1   (2) Plagioclase subgroup   It consists of sodium feldspar molecules and calcium feldspar molecules, which can be mixed in any ratio to form a continuous series of plagioclase analogues. It can be divided into six types: sodium feldspar, more feldspar, medium feldspar, labradorite, peperite, calcium feldspar, etc. Among them.   Sodium feldspar, containing 0-10% of calcium feldspar molecules, is produced in pegmatites, fine crystal rocks and schist.   Calcium feldspar, containing calcium feldspar molecules 90 ~ 100%, produced in gabbro and related rocks.   2. Chemical composition of feldspar   The feldspar species used in the glass and ceramic industry are mainly microplagioclase, orthoclase and sodium feldspar.   The theoretical chemical composition of potassium feldspar is: K2O 16.90%, Al2O3 18.40%, SiO2, 64.70%.   (Among them: orthoclase often contains sodium feldspar, more up to 30%; microcline feldspar is a more pure potassium feldspar, but it contains sodium feldspar, more up to 20%)   The theoretical chemical composition of sodium feldspar is: Na2O 11.80%, Al2O3 19.50%, SiO2, 68.70%   But the pure sodium feldspar is rare, the content of Na2O is often lower than the theoretical value, and contains K2O, CaO, etc. Second, the physical and chemical properties of feldspar Feldspar family minerals are generally white, gray, light flesh red, glassy luster, decomposition development, hardness of 6 ~ 6.5, density of 2.5 ~ 2.7g/cm3.   As an important industrial raw material, the melting point, melting interval and viscosity of feldspar have important application significance.   1. Melting point and melt interval   The melting point of potassium feldspar is 1290℃, sodium feldspar is 1215℃, and   Calcium feldspar is 1552℃, and barium feldspar is 1715℃.   The wide melting interval is also one of the excellent process properties of feldspar, and the melting interval varies with the content of feldspar components. Potassium microplagioclase feldspar in 1160 ~ 1180 ℃ is liquid, to 1210 ~ 1280 ℃ before completely molten.   2. Melting liquid viscosity   When feldspar is melted, the melt viscosity depends on the mineral composition, chemical composition and melting temperature of the ore.   At the same temperature potassium feldspar melt than sodium feldspar melt viscosity, and as the temperature increases, sodium feldspar melt quickly becomes a small viscosity easy to dilute the fluid, so that the ceramic blank deformation.   Because of the potassium feldspar melting point is not high, melting interval time is long, molten liquid viscosity and other advantages, so in the industrial use of more than other feldspar more widely     3. Chemical stability   Potassium feldspar glass and soda feldspar glass have a high degree of chemical stability, except for high concentrations of sulfuric acid and hydrofluoric acid, not subject to corrosion by any other acids, alkalis.   4. Fluctuating properties   The feldspar melt has a fluxing effect on other substances, and its fluxing ability is related to the temperature and the type of feldspar. Sodium feldspar melt has a greater fusion effect on quartz than potassium feldspar melt.  5. Easy to grind and grindability   The feldspar has good grinding and grindability due to the development of decomposition. The use of feldspar Feldspar is mainly used in glass and ceramic industry. The amount of feldspar in the glass industry accounts for 50%~60% of feldspar, the amount of feldspar in the ceramic industry accounts for 30%, and the rest is used in filler and other sectors.   1.Glass melting agent   Feldspar is one of the components of the glass mixture. It is mainly used to increase the alumina content in the glass ingredients, reduce the melting temperature and increase the alkali content in glass production, in order to reduce the amount of alkali.   Feldspar melt into glass process is relatively slow, crystallization ability is small, can prevent the formation of glass in the process of precipitation of crystals and damage to the product. Adjust the viscosity of the glass.   Generally used as a mixture of glass, such as potassium feldspar and sodium feldspar. Feldspar can also be used as glass fiber raw materials.   2. Ceramic blank raw materials   Before firing as a barren raw material to reduce the drying shrinkage deformation of the blank, improve drying performance, shorten the drying time.   When firing as a fusing agent to reduce the firing temperature, to promote the fusion of quartz and kaolin, accelerate the formation of mullite, so that the dense body and reduce the void, improve its mechanical strength and dielectric properties, improve the light transmission of the body. The amount of admixture is generally around 20%.   3. Ceramic glaze   Glaze is mainly composed of feldspar, quartz and clay raw materials, of which the content of feldspar up to 10% ~ 35%. In the ceramic industry (blank and glaze) is mainly with potassium feldspar.   Due to the feldspar fusion agent effect, so that the glaze melt fully. Feldspar glaze luster is good, smooth and transparent glaze.   4. Enamel raw materials   With feldspar and other mineral raw materials blended into enamel. The amount of feldspar blending is usually 20% to 30%.  5.abrasive   The production of grinding wheels used as ceramic cements components, the content of   28%~30%   6. Other   Feldspar with high potassium content can be used as raw material for extracting potassium fertilizer.   It is one of the raw materials for the production of white cement.   Paper, refractory materials, machinery manufacturing, coatings, welding rods, etc. as filler D. Sorting of feldspar According to the different types and nature of feldspar deposits, and the use of different beneficiation methods. In the past, it was generally crushed and ground after hand sorting, and then magnetic separation was used to remove iron minerals. Such sorting method has been criticized by the majority of feldspar sorting enterprises due to the high cost, low efficiency and the inability to be used on a large scale. In recent years, as the quality of feldspar ore decreases, the quality of the product requirements continue to improve, as well as the development of comprehensive mine recovery, the introduction of increasingly sophisticated technology of color separation equipment for sorting operations, so as to remove quartz, mica, iron and titanium and other associated minerals. After years of development, our company (Hefei Mingde Photoelectric Technology Co., Ltd.) has developed ore color sorting machine for ore sorting, which is also applied to feldspar sorting operation on a large scale. For feldspar sorting, we use the photoelectric principle to identify and analyze the color of feldspar, so as to carry out sorting. This way of sorting improves the quality and productivity of the product and realizes the value of the ore itself. After research and the use of the majority of mining enterprises to prove that the sorting of feldspar and the entire ore industry will use the ore color sorting machine to produce, which is the progress of the industry, but also the progress of the times, but also the trend of the development of ore. Take the road of fine processing, deep processing has come, the use of automated equipment sorting is imminent. Mingde photoelectric welcome all mining enterprises to visit our company.

Introduction   Construction waste is the waste generated in the process of building, maintenance and demolition, including waste concrete blocks, asphalt concrete blocks, mortar and concrete scattered during the construction process, broken brick slag, metal, bamboo and wood, waste from decoration, various packaging materials, etc., mainly solid waste.   For a long time, the reuse of construction waste in China has not attracted much attention, and it is usually transported to the suburbs or rural areas without any treatment and disposed of by means of open piles or landfills. The recycling of construction waste has become a major problem for urban construction. At the same time, there are still many materials in construction waste that can be recycled, and the immature construction waste treatment methods in China have invariably caused great waste of resources. The utilization rate of construction waste recycling in developed countries has reached 60% to 90%, or even 100%, while China is still less than 5%. Today, we share with you the experience of several developed countries in dealing with construction waste.   Japan   Japan regards construction waste as a "construction by-product" and attaches great importance to its reuse as a renewable resource. For example, port facilities and other infrastructure parts for renovation projects can use recycled stone to replace a considerable amount of natural quarry gravel material. Japan's leading policy on construction waste is to not transport construction waste from construction sites as much as possible and to reuse construction waste as much as possible. "Construction by-products" are divided into three categories: waste that cannot be used as raw materials, building materials that can be reused as raw materials (e.g. concrete blocks, wood), and building materials that can be reused directly (e.g. slag, metal). It can be seen that in the Japanese concept, the residual materials produced in the construction process are not all waste.   In Japan, there are more than 20 types of "construction by-products", and different laws apply to the disposal of different types of by-products. For example, weeds are treated as general waste, wood and construction sludge are treated as construction waste, metals are treated as industrial waste, asbestos, fluorescent light transformers and other toxic and hazardous substances are treated as specially managed industrial waste, and construction debris is not classified as waste.   Reducing construction site waste generation and reusing it as much as possible are the main principles of construction waste disposal in Japan. According to the "Outline for the Promotion of Appropriate Treatment of Construction By-products", construction project contractors and builders are obligated to reduce the generation of construction by-products during the construction process, and building material suppliers and building designers are obligated to produce and use building materials that can be recycled. Construction byproducts that can be reused should be reused as much as possible; construction byproducts that cannot be reused should be recycled as much as possible; and byproducts that cannot be recycled should be recycled by combustion to achieve heat recovery as much as possible.   In the past, Japan required the construction slag generated by piling and other construction slag to be transported out of the construction site, and then repurchased the slag when it was completed and backfilled, resulting in two transports and payments. In recent years, Japan has adopted a management approach to backfilling construction debris in place. The construction party can keep the slag excavated from piling in place at the construction site and then dispose of the remaining slag when it is backfilled to reduce the production of slag as much as possible.   Japan has a strict process to manage the production, sorting and disposal of construction waste. Construction teams are required to submit a detailed plan for the estimation, sorting and reuse, and final disposal of the waste that may be generated by the project to the construction company's headquarters, and to keep a report of the results for five years. If a company generates more than 1,000 tons of industrial waste in the previous year, it must submit a plan for waste reduction to the local prefectural governor by June 30 of that year.   A survey by the Ministry of Land, Infrastructure, Transport and Tourism showed that by the end of 2012, the re-resourceability of construction waste in Japan reached 96%, with the re-resourceability rate of concrete reaching 99.3%.   Germany   Germany's major cities suffered massive bombing in World War II, with Berlin and Dresden suffering over 80% damage to their buildings. Reconstruction requires a large amount of building materials, but Germany is a hundred years old, unable to produce. In such a situation, most of the construction waste was recycled, except for a few unmanageable building rubble that was dumped. The experience of reconstruction has fostered a renewed understanding in Germany that once put to good use, waste is also a resource.   Germany was the first country in the world to introduce legislation for a circular economy. After the introduction of the "Blue Angel" program in 1978, it enacted regulations such as the Waste Disposal Act, and in 1994 the Circular Economy and Waste Removal Act (amended in 1998), which has had a wide impact on the world. of recycled aggregates, and 175,000 housing units have been built with these recycled aggregates. At the same time, Germany levies a disposal fee of 500 euros per ton for unprocessed construction waste. The world's largest construction waste treatment plant is located in Germany, which can produce 1,200 tons of recycled construction waste per hour. There are about 200 construction waste disposal companies in Germany, with an annual turnover of 2 billion euros.   The "Georgswerder Energy Hill" on the banks of the Elbe in Hamburg is a classic example of waste recycling. Amidst the greenery, the white wind turbine blades slowly turn. Who would have thought that decades ago it was a dump for World War II bombing rubble and since then has been used for industrial waste and municipal garbage.   Wind power generator on the "Garbage Hill" on the Elbe River in Hamburg The garbage hill covers an area of 45hm2, the highest point being 40m above the ground, and was used for the reconstruction of Germany after World War II, when some of the construction waste could not be disposed of. Afterwards, Germany's industrialization took off and the scale of landfills became larger and larger. Until 1979, it was discovered that many companies had secretly buried a large amount of toxic chemical waste. The waste seeped into the ground and posed a threat to the safety of drinking water. A "rescue operation" was started.   The function of the "garbage mountain" Since the 1980s, the government has covered the mountain with a plastic waterproof film, laid a layer of soil up to 3m thick, and planted vegetation. In 2011, an 8,000m2 photovoltaic system was installed on the mountain, and a higher-powered wind turbine replaced the old motor. The electricity generated by both can meet the year-round needs of 4,000 households. The heat carried by the waste liquid generated by the garbage is also collected to heat the offices. In addition, a 1,000m long promenade was built at the top of the hill, which became the newest place for people to see the panoramic view of Hamburg. The garbage hill has become Hamburg's energy mound and a landscape park for the citizens. Panoramic view of the "Garbage Hill" According to German law, each responsible party in the construction waste production chain has to contribute to waste reduction and recycling. Manufacturers of construction materials must design their products to be more environmentally friendly and recycling-friendly. For example, they must produce panels in different lengths to avoid future re-cutting. Building contractors (including engineers and architects) must incorporate waste recycling into their construction plans. For example, use more recyclable building materials, etc. The responsibility of home demolition contractors is most critical. They are required by law to conduct demolition in a manner that facilitates the recycling of construction waste. In a highly competitive market, demolition contractors often obtain contracts from homeowners at very low or even zero prices. They then profit by breaking down, recycling and selling construction waste. This policy arrangement forces construction contractors and demolition operators to prevent contamination of construction materials to the greatest extent possible, as this not only results in reduced earnings for them, but also future payments for landfills or incineration.   Currently, using XRT intelligent sorting machine,Germany is one of the countries that does the best job of recycling construction waste, with a recycling rate of nearly 90%.   Singapore Data from Singapore's National Environment Agency shows that the country generated a total of 1,269,700 tons of construction waste in the year 2014, of which 1,260,000 tons were recycled, a recycling rate of 99%. About 8km south from Singapore's main island sits the world's first landfill developed from the sea, officially known as the Semakau Landfill, which consists of two small islands, Semakau Island and Sikyong Island, connected to each other and enclosed by the sea. In the 1960s and 1970s, Singapore relied on landfills around the island to dispose of solid waste, but by the late 1970s, limited land space forced the government to take steps to reduce waste generation and increase recycling rates. Singapore's "Semakau Landfill" Due to the economic value and market demand for construction waste such as steel bars, wood and concrete, waste collectors would sort the waste on site at the construction site by optical sorting machine and send it to the plant for recycling at a profit; if the waste was sent directly to the incineration plant or the Semakau landfill, the waste collectors would instead have to pay the corresponding waste disposal fees. Singapore's "Semakau Landfill"   As construction waste such as steel bars, wood and concrete have economic value and market demand, waste collectors will sort the waste on site at construction sites by garbage sorting equipment and later send it to factories for recycling and profit; if the waste is sent directly to incineration plants or the Semakau landfill, waste collectors will instead have to pay the corresponding waste disposal fees.   For construction waste recycling plants, the Environment Agency of Singapore also supports them by leasing out land, and these plants account for 80% to 90% of all construction waste recycled in Singapore. To maximize the recycling of construction waste, the Singapore government has introduced the Construction Demolition Code of Conduct, a set of procedural guidelines to help construction demolition contractors better plan the demolition process.   Government initiatives related to Singapore's focus on reducing waste generation at the source include the Green and Elegant Builder Program and the Green Building Mark Program. The former is a certification program launched in 2009 that rates building practitioners on a variety of aspects ranging from staff management, dust and noise control to public safety. The latter, which began in 2005, is a certification specifically for buildings in tropical regions that assesses the negative environmental impact of buildings and rewards their sustainability performance, assessing five areas: energy efficiency, water conservation, environmental protection, indoor environmental quality and other green features and innovations.   United States   The relevant U.S. law stipulates that any enterprise that causes industrial waste in its production must dispose of it properly by itself and must not dump it without authorization. This limits the amount of construction waste generated at the source, prompting enterprises to consciously seek ways to resource utilization of construction waste. For example, the American Home Builders Association promotes the "Resource Conservation House", whose walls are built with recycled tires and aluminum alloy scraps, most of the steel used in the roof frame is recycled from construction sites, and the panels used are made of sawdust and shredded wood plus 20% polyethylene.   South Korea   The Korean government enacted the Waste Recycling Promotion Act in 2003, which specifies the obligations of the government, dischargers and construction waste disposers and the requirements for capital, size, facilities, equipment and technical capacity of construction waste disposal companies. More importantly, it stipulates the scope and quantity of construction waste recycling products that construction projects are obligated to use and specifies what penalties will be imposed for failure to use construction waste recycling products as required. It is understood that there are currently 373 construction waste disposal enterprises in Korea.   Austria   Austria charges a high disposal fee for construction waste, thus increasing the cost of resource consumption. In addition, almost all enterprises that generate construction waste have purchased construction waste mobile processing equipment, and there are about 130 units (sets) in the country.   The Netherlands   In the Netherlands, 70% of construction waste can already be recycled, but the Dutch government wants to increase this percentage to 90%. Therefore, they have developed a series of regulations to establish a quality control system that restricts the dumping and disposal of construction waste and enforces recycling operations. An important by-product of construction waste recycling in the Netherlands is screened sand. Since sand is easily contaminated, its reuse is limited. In response to this, the Netherlands has adopted a sand recycling network where the picking branch is responsible for efficient sand screening, i.e. sorting according to its contamination level: storing clean sand and cleaning contaminated sand. In order to adapt to the new situation, MingDe XRF intelligent sorting machine, fully capable of fully sorting construction waste, municipal waste after incineration sorting, can effectively sort out the useful part, enhance the utilization of resources and reduce the volume of landfill.
