The separation of coal by water washing is still used in some traditional coal mines (mineral colour sorter). Since the coal has to be dried after washing, this process not only wastes water resources, but also entails higher labor costs and the risk of personal injury.

Zhongke AMD is the world's leading ore color sorter provider. After years of industry market research and technology accumulation, we have introduced the most advanced sorting equipment into the coal industry to help it achieve the goal of intelligent sorting and green mining.

Zhongke AMD ICS intelligent dry coal sorting machine integrates X-ray imaging, pneumatic rejection and big data processing technology to deeply identify different coal qualities and automatically remove gangue and impurities. This coal gangue sorting machine has the advantages of simple operation, convenient maintenance, resistance to harsh environments, low operating costs, and high sorting efficiency.

What are the main benefits of using optical sorting equipment for dry beneficiation?

1. Effectively reduce processing costs and improve product coal quality.
The gangue is discharged in advance, which effectively reduces the processing cost of the main washing system. At the same time, the X-ray sorting machine can accurately identify coal and gangue, and improve the quality of coal products.

2. Significantly reduce labor allocation and salary expenses
Taking the coal mine with an annual output of 4 million tons, there are 24 hand-pickers, and the intelligent sorting system can reduce the number of hand-pickers by 22, and the per capita wage insurance is 83,000 yuan/year, which can save 1.826 million yuan in labor costs each year.

3. Prevent workers from accidental safety accidents
Accidental safety accidents occur every year on the manual gangue-picking production line. The handling of gangue often hits hands and feet. The intelligent sorting system can realize unattended automatic sorting.

4. Reduce the number of mis-sorted coal blocks
Manual sorting has low efficiency, and the processing capacity per unit time is limited. Treating the coal lumps as gangue or reducing the belt speed for sorting will not only affect the efficiency, because mis-sorting will also bring a lot of losses to the coal mine. According to the statistics of coal mines, the number of mis-picks per year is thousands of tons.

5. After the gangue is discharged in advance, reduce the working load of the crusher

After the gangue is discharged in advance, it will save a lot of cost and the failure rate is low, avoiding the mine shutdown accident caused by the failure of the crusher. The gangue does not go through the water washing system and does not produce secondary slime, which reduces the load of the slime water system and reduces the cost of subsequent flotation.
