Dry Cleaning Process. Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. Abstract. Dry coal cleaning has claimed an important place in the current coal processing technology. The most important and reliable plants include rotary breakers, air jigs, FGX separators, air densemedium fluidised bed separators, radiometric sorters and others.
1. Coal Washing Plant (1). The excavator or loader feeds raw materials to the hopper of trommel scrubber; here trommel scrubber with 2layer screen at the end. After washing off the clay, screen three outputs: above 50mm,2050mm, and below 20mm. Above 50mm and 2050mm, outputs are transported to another place by belt conveyors. (2).
The heavy medium recovery technique used in coal washing plants mainly includes the optimization of process parameters of the heavy medium recovery system (screen hole, combination, and slime content treatment) and drum magnetic separator characteristics [11], [12], [4], [13], [14], [15].
