我厂的精矿选别是采用φ750×1800毫米永磁式磁选机。它的筒体保护层是用环氧树脂粘合25×4毫米胶条于其表面。这种保护层的优点是使用周期较长,但有更换工艺复杂、工时多、费用高缺点。经常由于局部发生割划,导致整台设备的胶条脱落。因此,在我厂使用半年左右就得进行维修更换,给生产带来影响。嗣 My factory concentrate selection is the use of φ750 × 1800 mm permanent magnetic separator. Its cylinder protection layer is epoxy bonded 25 × 4 mm strip on its surface. The advantages of this protective layer is the use of a longer period, but there are complex replacement process, working hours, high cost disadvantages. Often cut due to a partial occurrence, leading to the entire equipment strip off. Therefore, in our plant about six months or so have to carry out maintenance and replacement, to produce an impact.
