Description

Technical Field

[0002] Coal gangue is industrial solid waste generated during coal mining and washing. It is a black-gray rock that accompanies coal seams during the coal formation process. It has a low carbon content and is harder than coal. Its types include excavation gangue during tunnel excavation, natural gangue mined from the roof, floor and interlayer during mining, and coal selection gangue sorted out during coal washing. Coal cinder and coal ash are industrial solid wastes generated by coal chemical industry, more than 90% of which is ash and has a very low carbon content.

[0003] The amount of coal slag and coal gangue produced is huge, and it is impossible to dispose of it on a large scale in time. They can only be stored on site, which occupies land and brings environmental pollution risks to the local area. At present, some coal slag and coal gangue crushed materials are added to curing agent and then mixed with water, and then extruded into building materials for recycling. However, when recycling coal slag and coal gangue in this way, it is currently impossible to fully mix the coal slag and coal gangue in an integrated manner, resulting in inadequate crushing and uneven mixing of the coal slag and coal gangue raw materials during the recycling process, resulting in poor quality of the recycled raw materials.
