新研制的M-CCTB154永磁筒式磁选机采用阶梯式复合磁系,磁包角135°,分选粒度8～0mm,平均磁感应强度190mT,处理量可达120～250t/h,为我国选别设备大型化提供了新的高效设备。在南芬选矿厂一段选别的工业试验表明,与原CTB1232磁选机比较,精矿品位基本持平,尾矿品位降低0.17个百分点,精矿回收率提高0.28个百分点。 The newly developed M-CCTB154 permanent magnet barrel magnetic separator with step-type composite magnetic system, magnetic wrap angle of 135 °, sorting granularity of 8 ~ 0mm, the average magnetic flux density of 190mT, the handling capacity of up to 120 ~ 250t / h, for our country Large-scale sorting equipment provides a new high-efficiency equipment. A selection of industrial tests at the Nanfen Concentrator indicated that the grade of concentrate was basically the same as that of the original CTB1232 magnetic separator, the tailings grade decreased by 0.17% and the concentrate recovery rate increased by 0.28%.
