强磁选是选别弱磁性铁矿石的重要方法之一。最近几年研究和应用的永磁环式磁选机就是其中的一种。马钢南山铁矿选矿厂自1965年投产以来,生产指标逐步提高。近年来采用永磁环式磁选机代替原有的双联三层摇床,选别弱磁选尾矿中的弱磁性铁矿物后,选别指标又有新的改善:在弱磁性铁精矿品位大体相同的情况下,含磷量有较大的降低,铁回收率有较大的提高。经过两年多的生产实践证明,用永磁环式磁选机选别凹山铁矿石中的弱磁性矿物与三层摇床比较,具有台时处理能力大,占地面积小,
Strong magnetic separation is to choose the weak magnetic iron ore one of the important ways. In recent years, research and application of permanent magnet ring magnetic separator is one of them. Mansang Nanshan Iron Ore Concentrator since its commissioning in 1965, production indicators gradually increased. In recent years, the use of permanent magnetic ring magnetic separator instead of the original double triple-layer shaker, weak magnetic separation of weak magnetic iron ore tailings, the sorting index has a new improvement: the weak magnetic iron Concentrate grade is generally the same case, a greater reduction in phosphorus content, iron recovery rate has greatly improved. After more than two years of production practice has proved that the use of permanent magnetic ring magnetic separation machine concave Hill iron ore weak magnetic minerals compared with the three-tier shaker, with Taiwan's handling capacity, small footprint,
