Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Coal gangue is a kind of solid waste, which is usually stacked in the open air, and this treatment method not only pollutes the atmosphere, farmland, and water sources, but also has the hidden danger of spontaneous combustion. However, in recent years, with the development of technology and the improvement of environmental protection awareness, the utilization of coal gangue has ushered in a new life.

The use of coal gangue

1. It can be used to generate electricity. It is mainly used to generate power by co-firing washed medium coal and washed gangue. Coal gangue power generation and heating are an important way to use coal gangue in my country at present. Coal gangue power generation not only provides new energy for coal mine production, At the same time, it also brings huge economic and social benefits.

2. It can be used for brick making. The cost of building bricks is greatly reduced by using coal gangue instead of clay, and there is no need to water before building walls and painting, which saves water and labor costs. Due to the high hardness, the loss of products during transportation Also lower than clay bricks.

3. It can be used as pavement material. Coal gangue that meets the requirements of burning expansion can be made into coal gangue ceramsite after crushing, preheating, burning, cooling and grading. Coal gangue ceramsite can be widely used in highways and airport runways pavement material.

4. It can be used as filling material. When coal gangue is used as filling material to fill the goaf, the method of layered filling should be adopted, and each layer should be rolled and sprayed with lime water separately, so that better foundation stability and bearing capacity can be obtained ability In addition to the above 4 points, coal gangue has many uses after treatment. Crushing and sand making are common treatment methods for coal gangue. There are many processing equipment suitable for coal gangue. So what are the small gangue crushers? What is the price? Coal gangue crushers

1. Double Roll Crusher

Double roller crusher is a very common coal gangue crushing equipment. It uses two sets of independently driven roller shafts to crush materials by the extrusion force and grinding shear force generated by relative rotation. The crushing force is strong and the output particle size is adjustable. The overall structure of the double roll crusher is simple, low investment and high economic benefit.

2.Twin Shaft Mineral Sizer

Mineral sizer is featured with low power consumption, big capacity, simple structure, light weight and energy saving. FP series mineral sizer is a new conception crusher, which is completely different from the traditional toothed roll crusher of which crushed material and ores by impact and squeezing force.More tooth pattern choice for more efficiency crushing and low energy consumption.

How much is a coal gangue crusher?

The price of the crusher is positively correlated with the production capacity of the crusher. The production capacity of the small coal gangue crusher is relatively small, so the price is also more favorable. Generally, a small coal gangue can be purchased for tens of thousands or hundreds of thousands. The shredder is gone. Due to the differences in production costs, technical processes, and equipment material selection of different manufacturers, there is no unified quotation. It is recommended to directly consult the equipment manufacturer for specific prices.
