汪家寨洗煤厂重介质选煤系统,使用渡口选矿厂磁选后的钒钛磁铁矿粉作加重剂。该加重剂磁化后剩磁较大,用原有的退磁器难于退磁。不经退磁的钒钛磁铁矿粉,在水中出现明显的磁凝聚现象,大大地加快了沉降速度,使悬浮液的稳定性很
Wangjiazhai coal washing plant HM cleaning system, the use of ferrredit after ore dressing plant magnetite vanadium titanate as a weighting agent. The weighted magnetic remanence magnetization larger, with the original demagnetizer difficult demagnetization. The vanadium-titanium magnetite powder without demagnetization shows obvious magnetic cohesion phenomenon in water, greatly accelerating the settling velocity and making the suspension stable
