Indonesia, as one of the countries with the richest limestone resources in the world, has a limestone reserve of approximately 34 billion tons and a proven reserve of approximately 28 billion tons. It is mainly distributed in the southern part of West Java, East Java, Papua Province in the east, Bali, and the north and south ends of Sumatra Island.

        With the surge in demand for limestone in the global market, how to balance "quality and output" has become a concern for limestone producing countries, including Indonesia.

一、What are the advantages of Mingde color sorter

       The Mingde color sorting machine adopts advanced photoelectric sorting technology, based on the RGB three primary color principle to identify and sort the surface color and transparency of ores, and has the following advantages:

     Firstly,it is high accuracy and efficiency,compared with traditional methods, Mingde Optoelectronics' color sorting machine has increased sorting speed by more than 30% and sorting accuracy by more than 20%. This means that companies can process more ore in the same amount of time, while reducing the defect rate and improving the market competitiveness of finished ore.

      Secondly, it has reduced operating costs,according to the calculation,After using Mingde Optoelectronics' color sorting machine, the sorting cost per ton of limestone has been reduced by about 15%. In addition, the maintenance cost of the equipment is relatively low, and in the long run, the overall operating cost of the enterprise has been effectively controlled.

      Thirdly,improve the quality of ore.For limestone sorting of 1-5cm, it is possible to choose between one-time sorting to produce finished ore based on the actual quality of the ore, or two rounds of sorting to select first grade, second grade, and waste rock respectively.

       The last point is compliance with environmental protection requirements.Optoelectronic beneficiation belongs to physical beneficiation, which meets the requirements of national and local governments for environmental protection, helps enterprises establish a good social image, and enhances market competitiveness.

二、Analysis of Practical Application Cases of Mingde Color Sorter in Indonesia

    After years of market research, an Indonesian limestone production enterprise ultimately chose Mingde Optoelectronics' color sorter. The enterprise mainly produces 1-5cm limestone and has been using traditional manual sorting methods, which not only have low efficiency but also low sorting accuracy, resulting in uneven product quality and weak market competitiveness.

     After introducing the color sorting machine from Mingde Optoelectronics, the company achieved automated sorting, significantly improving sorting speed and accuracy, and ensuring product quality.Specifically reflected in the following aspects：

      Firstly, the sorting speed has increased by 200%, and the amount of ore that can be processed per day has increased by 300%.

       Secondly, the sorting accuracy has been improved by 20%, and the defect rate has been reduced by 15%.

       Thirdly, the sorting cost has been reduced by 15%, and the maintenance cost has been reduced by 10%.

Fourthly, the quality consistency of finished ore has significantly improved, and the market recognition has greatly increased.

三、conclusion

       Mingde Optoelectronics' artificial intelligence color sorter has become a leader in the Indonesian limestone market due to its excellent technical performance and economic advantages. By improving sorting accuracy and efficiency, reducing operating costs, enhancing product quality, and meeting environmental requirements, Mingde Optoelectronics' color sorting machine has brought tangible economic benefits to enterprises, helping them stand out in fierce market competition.

      With the continuous advancement of technology and the continuous development of the market, Mingde Optoelectronics' color sorter will undoubtedly play a more important role in the limestone industry in Indonesia and even globally.
