Coal gangue is the solid waste discharged during the coal mining process and coal washing process. It is a kind of black-gray rock with low carbon content and harder than coal that is associated with the coal seam during the coal formation process. Coal gangue is rich in metals, alkaline earth metals and sulfides, and contains a large amount of organic components. It is easy to pollute the environment when it is leached by atmospheric precipitation.
With the improvement of people’s living standards, the speed of urban construction increases, more and more waste metals need to be processed, and the coal gangue crusher can not only be used for coal gangue and other materials, but also for construction industries such as slag, cement, river pebbles, etc. And the crushing of materials in other industries. More importantly, the materials crushed by the gangue crusher can be widely used in metallurgy, building materials, chemicals, mines, highways, railways, water conservancy, chemicals and concrete mixing plants and other industries. So, what equipment is used to process coal gangue?
1. Coal gangue jaw crusher – coarse crushing
The coal gangue jaw crusher is a coarse crushing equipment. When processing coal gangue, this equipment is characterized by large crushing force, large bearing capacity, more stable operation, convenient maintenance for users, and less failures.
2. Coal gangue impact crusher, coal gangue roller crusher – medium and fine crushing
The coal gangue impact crusher is mainly for medium and fine crushing of coal gangue. The new heavy-duty rotor has higher crushing efficiency and high comprehensive benefits. The finished product is cubic, without tension and cracks, and the product has a stable and better grain shape;
The coal gangue double-roller crusher adopts the principle of extrusion and rolling crushing for crushing coal gangue. The wearing parts have longer life, less loss, high production efficiency, simple structure, convenient maintenance and low operating cost.
3. Coal gangue vertical compound crusher – fine crushing
The coal gangue vertical composite crusher can achieve more crushing and less grinding, and is an ideal fine crushing equipment for energy saving and consumption reduction. Its main features are straight cylinder crushing cavity, high output, special water-cooled structure design can crush high-temperature materials, high efficiency and energy saving, and stable operation. It is suitable for crushing medium-hard ores, such as medium-soft iron ore, sandstone, gypsum, blast furnace slag, coal gangue, lump coal, metallurgical solvent raw materials, etc.
