zkj/ Release time : 2023-03-03

Coal gangue is a solid waste discharged in the process of coal mining and coal washing, it is a kind of coal formation process and coal seam semi-born black rock with low carbon content and harder than coal. Coal mining is an important source of energy in China, the annual mining volume is huge, the discharge of coal gangue also increased, coal gangue abandoned, will occupy a large area, may also pollute the land and ecological environment, therefore, coal gangue waste reuse has been an important subject of research in China. With the rapid development of China's urbanization, the demand for bricks has increased greatly, because the clay brick making destroys the land, pollution, high cost, has been explicitly prohibited by the government, and coal gangue can just replace the clay brick making, therefore, coal gangue brick making is a good project for the benefit of the country and the people. Now China's coal gangue brick technology has been quite mature, made of high hardness, low cost bricks, economic benefits are very considerable, and also subsidized by government departments, become a hot investment projects.

"I have a coal washing plant, washing down the gangue can not be lost ah, open a coal gangue brick plant to use which equipment?"

"My home near a large coal mine, every year there are more than 100,000 tons of coal gangue output, I want to open a coal gangue brick factory, how much investment is needed?"
