Technological practice of capacity expansion transformation of coal preparation plant in Changxing coal mine
LIU Hai-xia
Abstract：Because that raw coal of coal preparation plant in Changxing coal mine had relatively high ash content, the cleaned coal yield was restricted, combining with the spot actual circumstance, the preparation workshop, main washing system and existing of curved screen were analyzed specifically, partial transformation plan of process was proposed to improve the separating capacity of movable-sieve jigger and TBS separator, meanwhile, the production pressure of heavy medium system could be reduced, the coal quality change of coal mine could be adapted.
