Technical transformation practice of coarse coal recovery system in Fucun Coal Preparation Plant
In order to solve the problems in the coarse coal slime recovery process system of Fucun Coal preparation Plant,the transformation was completed by upgrading the inclined plate precipator system,using the ZKJ series laminated screen to replace the original graded cyclone and high frequency screen process system,and optimizing the management of screening water.The transformation results show that it solves the problems of mismatches,poor grading effect and high ash content of the high frequency screen,ensures the efficient and stable operation of crude coal sludge link,improves the recovery rate of crude cleaned coal,reduces the burden of flotation system,and avoids the problem of low ash content of heavily cleaned coal to make up the high content of coarse concentrate coal.
