齐大山选矿厂于1966年研制一台电磁筒式强磁机。这台磁选机是在圆筒外加辅助磁机。形成闭路磁系。高场强是由尖齿—平面磁极对形成的。这种磁选机制成后,经试验存在严重的堵塞问题,不能使用。现在,齐大山选矿厂要利用这台磁选机进行阶段选矿,利用它的高场强甩掉一部分合格尾矿。根据齐大山选矿厂的要求,为解决堵塞问题,对这台磁选机存在的问题进行了考查,并提出分析和改进意见。由于没有完整的资料可查,所提分析和改进意见可能局限性很大。
Qi Dashan Concentrator in 1966 to develop a magnetic cylinder-type magnetic machine. This magnetic separator is attached to the cylinder auxiliary magnetic machine. Formation of closed-circuit magnetic system. High field strength is formed by cusp-plane pole pairs. After the preparation of this magnetic separator, the test there is a serious blockage problem, can not be used. Now, Qidashan concentrator to use this magnetic separator stage dressing, using its high field strength to get rid of part of the qualified tailings. According to Qidashan concentrator requirements, in order to solve the blockage problem, the problems of this magnetic separator were examined, and the analysis and improvement suggestions were put forward. In the absence of complete information to be investigated, the analysis and suggestions for improvement may be very limited.
