摘　　要：济宁二号煤矿选煤厂通过实施中矸磁尾分开单独回收的技术改造,将高灰矸石磁尾改为单独脱水回收后进入矸石系统外排,并增加煤泥离心机对中煤磁尾进一步脱水,有效降低了洗混煤产品的灰分和水分,提高了洗混煤发热量,取得了良好的经济效益。Through the implementation of technical transformation of separate recovery of gangue magnetic tail,Jining No.2 Coal Mine Coal Preparation Plant has changed the high ash gangue magnetic tail to separate dewatering and recovery,then discharged it into the gangue system,while adding slime centrifuge to further dehydrate themidding magnetic tail.It also effectively reduces the ash and moisture of washed blended coal products,improves the calorific value of washed blended coal,and achieves good economic benefits.
