Gangue is a kind of black waste rock which is discharged in the mining
process containing small amount of carbon. Gangue is the solid waste with the
largest emissions in China, whose emissions and accumulation not only take up a
lot of arable land, but also has caused a lot of pollution of the surface and
the atmosphere. The chemical composition of the gangue is similar to the clay.
The gangue contains high carbon and sulfur with large loss on ignition. Only in
a certain temperature range can enough molten material with appropriate
viscosity be produced, which has expansion properties.
Gangue is can be recycled to be re-used. After the gangue is crushed by the crusher to achieve the required particle size, it can be added to the production process of ceramics, cement, brick, etc. In fact, the reutilization technology of the gangue in our country has been already quite mature, but the reutilization rate of the gangue is relatively low. The reason is that the traditional crusher on crushing technology of the gangue is not too successful. The development of crusher industry in China is very optimistic and the technical strength has reached a certain height. The practice has proven that the impact crusher produced by Henan Hongxing Mining Machinery has a very significant effect on the reuse of the gangue and the recovery rates can be as high as 89%.
For example, after the gangue is crushed by the impact crusher, it can be applied in the ceramic. The gangue ceramisite is to use the gangue which is consistent with the burn expansion requirements to produce the gangue ceramisite through crushing, preheating, burning swelling, cooling, grading and packaging. The quality of the ceramsite product quality is in full compliance with national standards, and some technical indicators exceed the national standards which has reached a level of the similar foreign product quality. This kind of the product is innovative, advanced and it belongs to the environmentally friendly product.
The technical application of the gangue on ceramic is a major technological breakthrough of the recycle of the gangue. The impact crusher produced by Henan Hongxing Mining Machinery can make the recovery rates of the gangue as high as 89%, which rewrites the history of low utilization rate of the gangue and opens a new chapter of the gangue on the respect of the low carbon environmental area.
