Study on the design of coal washing processes of Haizetan Coal Preparation Plant

The paper starts with an analysis of the property of the raw coal treated by Haizetan Plant and the use of the clean products by targeted users, and then goes to introduce the basis for selection of washing schemes and the feed size range for each washing process. The plant is designed to treat the 80~13 mm coarse coal using the heavy medium shallow-bath separator. The system has the reserved capacity to treat the 13~6 mm small coal. The ＜6 mm finer coal is left untreated for the time being yet the capacity is kept in reserve for its treatment when needed. The coal slime is recovered by filter press.
