Coal gangue roller screen screening site

In the coal mining industry, China produces 100 million tons of coal, discharge about 14 million tons of gangue, in the coal washing industry, each washing 100 million tons of coking coal, discharge 20 million tons of gangue, each washing 100 million tons of thermal coal, discharge 15 million tons of gangue. As a big coal producing country in the world, China has a large amount of coal gangue, which can realize the utilization of resources, improve the ecological environment of mining areas, and ensure the green and sustainable development of modern coal enterprises. The user collects coal gangue from the mine, which varies in size, sometimes the material is sticky, and the gangue is also mixed with wood and steel bars and other debris, which can not be screened with traditional screening equipment. In the case that the user can not solve, found my unit customized a coal gangue roller screen, the screening effect is very satisfied after use, different coal gangue particle size and debris separation, sales to different fields, making the added value of coal gangue increased, the user's benefit also increased. Science popularization: The use of coal gangue to prepare building materials, mainly including brick, cement raw materials, ceramic materials and so on. Making bricks. Brick making from coal gangue usually uses the calorific value of coal gangue itself to provide the energy required for drying and baking. The calorific value of coal gangue in China ranges from 3300 to 6300 kJ/kg[5]. When the calorific value is low, part of coal can be added for production, so the use of coal gangue to make bricks can significantly reduce energy consumption.
