Coal gangue is solid waste discharged in tunneling, mining and washing process. Gangue disuse, occupy large tracts of land.The sulfide escaped from gangue will pollute the atmosphere, farm and and water. Waste dump will be spontaneous fires or landslides during the rainy season, silting rivers to cause disasters. China accumulated more than 10 million tons of coal gangue, 100 million tons per year will be discharged. In recent years, coal is no longer just as a number of the largest industrial solid waste and has been widely studied and applied as a resource in the chemical industry, building materials, metallurgy, light industry and other fields.

Gangue crusher replaces the earlier single-stage crusher with sieve bottom and perfectly solve the difficult issues for crushing humidity of materials.effectively saving the customers’ cost. The machine has the features of large capacity and low noise.It is easy to maintain and can be start using immediately without special installation. Gangue crusher adopt double rotor up and down two-stage crushing, no screen and grate bottom, the moisture content of the material is not strictly required.There is no problems such as paste blocking sieve, more powder can not be discharged, repeat crushed. Therefore, it has high grinding efficiency and there is no hammer invalid wear and tear. High wear-resistant alloy hammer, hammer wear without repair, mobile location repeated use, a hammer top three hammerhead.
