In the case of increasing shortage of coal gangue, with the deepening of the economic system reform and the healthy and rapid development of our country's industry and agriculture, mining machinery enterprises are increasingly focusing on energy-saving gangue mill R & D and production, in the manufacturing of mining machinery, long life, low energy consumption, lightweight design principles, mining machinery and equipment enterprises are increasingly focusing on energy-saving, environmentally friendly gangue mill.

Coal is China's main energy source, plays a pivotal role in social and economic development. The development and utilization of coal, while promoting social and economic development, also has a significant impact on the environment. Coal gangue and coal bed methane (CBM), the main wastes produced during coal mining, have been regarded as hazardous substances and disastrous gases by the coal industry. Solid waste generated during coal mining, extraction and washing. In recent years, coal gangue in the chemical industry, building materials, metallurgy, light industry and other industries have been widely studied and applied, coal gangue as a resource has been widely used in the chemical industry, building materials, metallurgy, light industry and other fields, coal gangue resources has become the current research hot spot.

The main use of coal gangue

1.Recovery of coal and pyrite

A simple process is used to wash and select coal from the gangue, screened and selected pyrite. Or from the selection of coal jigging machine - in the process of plane shaker recovery of pyrite, mixed coal and coal. Recycled coal can be used as fuel for power boilers, washed gangue as building materials, pyrite as a chemical raw material.

2.Power generation

Power generation is done by washing middle coal and washing gangue mixing. In China, the use of boiling furnace combustion of washed coal and washed gangue (calorific value of about 2,000 kilograms per kilogram) to generate electricity. Slag can produce slag bricks and cement.

3. Manufacture of building materials

Instead of clay as raw materials for bricks, less good land can be dug. When burning bricks, the use of gangue itself combustible, can save coal. Whether making bricks with gangue, recycling coal and pyrite, or producing cement additives or providing raw materials to gangue power plant or to gangue power plant, usually use jaw crusher, LM vertical mill, vibrating screen, vibrating feeder and so on.
