When working, the coal is fully washed under the flushing action of water stream, and then enters the dewatering vibrating screen. Under the action of vibration, the clean coal and mud water are separated, and the clean coal water content is controlled within 10%-15%, thereby achieving the transportation or dry stack.

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.

The process of cleaning coal is a wet one, using large quantities of water (i.e., thousands of gallons per minute). As a result, vast quantities of dirty (fine rock-laden) water are produced. Beneficiation processes require clean water. Consequently, dirty water is processed, solids removed, and clean water recycled for further use in the plant.
