摘　　要：加重质净化回收对流态化连续分选过程的床层密度稳定和介耗有着重要影响。为此,考察了操作参数对干法磁选净化效果的影响。结果表明,磁链是影响干法磁选净化效果的重要因素。The purification influence on bed density and recovery of heavy medium by magnetic separation has an important and magnetite powder loss in continuous separation. Therefore, the experiments were carried out to investigate the influence of operation parameters on the efficiency of purifying fine coal from magnetite powder. The results show that magnetic linkage is one of key factors that have an important influence on magnetic efficiency.
