Description

A coal gangue waste recycling device

technical field

The invention belongs to the technical field of waste treatment, and in particular relates to a coal gangue waste recovery treatment device.

Background technique

Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing process. The coal gangue is discarded and occupies a large area of land. The escape or leaching of sulfide in coal gangue will pollute the atmosphere, farmland and water bodies. Gangue hills can also spontaneously ignite and cause fires, or collapse during the rainy season, silting up rivers and causing disasters. The accumulated coal gangue in China has reached more than 1 billion tons, and 100 million tons of coal gangue will be discharged every year. In order to eliminate pollution, since the 1960s, many countries have begun to pay attention to the treatment and utilization of coal gangue. The mined coal gangue usually needs to be crushed and screened to turn it into a low-carbon building material that is conducive to environmental protection.
