As the biggest coal production country in the world,China kept abundant of coal gangue.This brings a huge environment problem.The low efficiency and high cost of traditional sorting processes have led to a vicious cycle of "more treatment, more accumulation" in the treatment of coal gangue.

However, with the breakthrough of X-ray intelligent sorting technology, a revolution is quietly happening to reshape the industrial logic from the source.

一、X-ray Sorting Tech:a Big Revolution for Coal Gangue Handling

Coal gangue is not a worthless waste material. 15% -30% residual coal, 40% -70% aluminosilicate, and 3% -8% pyrite in its composition can theoretically be converted into power generation fuel, building materials, and even rare metal extraction sources.

Mingde Optoelectronics' X-ray intelligent sorting equipment is changing the awkward position of coal gangue as "solid waste". When coal gangue enters the detection area, Mingde Optoelectronics' X-ray combined with high-precision dual energy transmission technology instantly penetrates the material, accurately capturing the subtle differences between coal and gangue.

Combined with Mingde's self-developed intelligent sorting technology for identification and sorting, this system is like giving value to coal gangue.

二、Mingde's Optoelectronic Sorting Tech:Made Coal Gangue a Treasure

If the intelligent sorting equipment is placed in front of the main washing system, it is like installing an "industrial CT" on the production line. Originally 25-300 millimeters of raw coal, after the pre discharge of gangue, the amount of gangue mixed in can be reduced by 38%, and the ash content of clean coal can be reduced by 1-2 percentage points.The deeper significance lies in the fact that coal gangue can also create high profits.

三、New Logic for Reconstructing the Coal Industry From Mingde's Optoelectronic Sorting Tech

The impact of this technological revolution has long exceeded the scope of environmental protection. The application of pre sorting system in mining areas can increase the washing rate of raw coal from 65% to 90%, and reduce the energy consumption of ineffective transportation by 18%;

The promotion of dry sorting technology has reduced the carbon intensity of coal preparation plants from 8.9kgCO2/ton to 3.2kgCO2/ton; The emergence of specialized sorting service providers has given rise to a new business model of "charging by ton".

In the coming years, the resonance effect between policies and technology will gradually emerge.
