我矿选矿厂使用的φ750mm×1800mm半逆流永磁磁选机,在生产使用中简皮保护层常磨损和破损,从而导致不透钢筒皮直接和矿浆接触,缩短筒皮的使用寿命,严重时局部被磨出漏洞,更换一个圆筒造价2万元。磁选机筒皮原保护层为树脂类耐磨保护层。经生产使用证明,这样的保护层耐磨期较短(一般6个月左右),而且磨损后易破碎成片脱落。采用这种树脂类耐磨保护层的缺点是:现场处理困难,重新 The φ750mm × 1800mm Semi-Countercurrent Permanent Magnetic Separator used by our ore beneficiation plant often wear and break the protective cover of the skin in production and use, resulting in the direct contact between the impervious steel cylinder and the pulp, shortening the service life of the cylinder, serious Local time was ablated loopholes, replacement of a cylinder cost 20,000 yuan. Magnetic separator drum original protective layer of resin wear protective layer. Proved by the use of production, such a protective layer wear short (usually 6 months or so), and easily broken into pieces after wear and tear off. The disadvantage of using this kind of resin wear protective layer is that it is difficult to deal with the scene and restart
