Coal washing equipment is composed of multiple sets of different mechanical equipment. Generally, the purchaser appears as a complete set. Those who are knowledgeable will not say where the problem lies with the coal washing equipment, but rather a specific equipment such as a jig and flotation machine; The raw coal undergoes preparation, sorting, dehydration, drying, and final processing to complete the washing process. The working principle of the coal washing equipment was introduced a few days ago by the editor, and you can review it again.

　　Among them, the coal washing equipment needs to first receive the raw coal, store, crush, and screen it, and use a jigger for flotation. The lump coal, fine coal, clean coal, and coal slurry in the raw coal need to be dehydrated, and then dried using thermal energy. After treating the coal slurry water, it can be used. In response to low-carbon environmental protection policies, it is filtered and recycled, so there is no need to worry about wasting water.

　　When the coal washing equipment screens out products of two or more levels, there is a problem with the arrangement order of the sieve surface with a large and small sieve hole. The material sent into the sieve for screening is called the incoming raw material, the material that does not pass through the sieve hole is called the screened material, and the material that passes through the sieve hole is called the screened material; A screening sequence from small to large can be adopted, first screening out the fine coal particles in the material, and then gradually screening out the coal blocks with larger particle sizes; It is also possible to use a screening sequence from large to small, first screening out coal blocks with larger particle sizes, and then gradually screening out coal blocks with smaller particle sizes.

　　Due to the fact that large blocks of coal in the material are screened out first, the phenomenon of collision and crushing of large blocks of coal on the screen surface is reduced. Therefore, the screening sequence from large to small is widely used in coal washing equipment. The coal amount on the small screen hole screen surface is reduced, allowing more opportunities for difficult to screen fine coal to pass through. The screen surfaces of each layer are overlapped and assembled, and the screen occupies a smaller area of the factory building.
