A study of the process flowsheet of Jingtai Energy Group′s Coal Preparation Plant

In order to be able to produce the coal products that can meet the integrated requirements of both upstream and downstream industrial sectors, a study is made of the plant′s coal cleaning methods based on analysis of the property of the raw coal treated. Result of study shows that the coal products can meet the demand if the raw coal is treated using a combined process: predesliming of raw coal + washing of > 13 mm size with H.M. vessel+primary and secondary washing of < 13 mm size using pressure-fed 2-product H. M. cyclone + separation of coarse slime with spiral separator + recovery of fine slime with quick-open membrane filter press.
