How to make use of coal gangue by ultra fine powder machine

Coal gangue is solid waste produced by coal digging and washing. Coal gangue and coal bed gas are the main waste in coal’s exploitation, and are regarded as the hazardous material and hazardous gas.

There are three ways to make use of coal gangue by ultra fine powder machine: making building material; recycling coal and pyrite; producing electricity. Scientists have done a lots exploration and researches, and got achievements. In impleting strategy of sustainable development ,comprehensively taking advantage of coal gangue is paid attention. We should insist on opening up and saving resource, put cyclic utilization in a important place, turn waste into available resources.

Features of Coal gangue ultra fine powder machine:

High efficiency
Under the same finished final size and the same motor powder, the capacity of micro powder grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.

Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3 times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5years for grinding calcite carbonate.

High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearing and seal components.

High fineness and flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 25oo meshes, and the product fineness can reach D97≤5μm.

Environment-friendly
The application of pulse of pulse bag filter and muffler greatly alleviates dust pollution and noise.

Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
