Coal Gangue Grinding Mill Unit, 20TPH, 120 Mesh for Building Material & Cement Admixture
Coal gangue is a kind of industrial solid waste associated with coal mining, with large annual output and low comprehensive utilization rate. Long-term accumulation of coal gangue will occupy land resources and cause environmental pollution. After professional grinding and activation treatment, coal gangue powder has good volcanic ash activity and can be widely used in building materials, cement admixtures and road engineering filling materials.
The resource utilization of coal gangue through grinding processing is an important green environmental protection project in the modern coal industry. This coal gangue grinding project adopts a large heavy-duty grinding mill production line, with an hourly output of 20 tons and finished powder fineness of 120 mesh, dedicated to large-scale harmless and resource-based treatment of coal gangue solid waste.
Raw coal gangue has certain hardness and humidity, and contains a small amount of residual coal components. Before grinding, the bulk coal gangue is crushed, dried and impurity-removed to eliminate agglomeration and ensure uniform feeding. The heavy-duty grinding mill has strong adaptability to gangue raw materials, and can fully grind and activate the internal mineral activity of coal gangue.
The processed 120-mesh coal gangue powder has stable activity and good bonding performance. When mixed into cement and concrete, it can effectively improve the compressive strength and durability of concrete products, reduce the dosage of cement clinker, and greatly reduce the production cost of building materials.
In addition, coal gangue powder can be used as the main raw material for sintered environmental protection bricks and permeable bricks, realizing waste recycling and replacing natural clay resources. It can also be used as road base filling material to improve the compactness and bearing capacity of road foundations. This 20TPH coal gangue grinding production line has high automation degree and large daily processing capacity, which is suitable for large coal enterprises and building material factories to realize centralized treatment of solid waste.
The equipment is optimized with anti-sticking and anti-blocking structure, which can adapt to long-term grinding of wet and viscous gangue materials. The whole production process is energy-saving and environmentally friendly, conforming to global low-carbon and green development policies. This project not only solves the environmental pollution problem of coal gangue accumulation, but also turns industrial waste into high-value building material raw materials, realizing the perfect combination of environmental benefits and economic benefits.
