近年来对浮选机性能提出的要求是:最高的选矿回收率,降低电能消耗,增加设备使用的可靠性和耐久性。由于现代选矿厂大都使用机械(叶轮)式浮选机而造成的每年为更换叶轮和盖板而花掉了许多钱。因此迫切需要制造结构更为合理的浮选机。最近苏联曾进行了两种浮选机的试验,都取得了一定的效果。 In recent years, the requirements of flotation machine performance are: the highest ore dressing recovery rate, reduce power consumption, increase the reliability and durability of equipment. Due to the fact that most of the modern beneficiation plants use mechanical (impeller) flotation machines, they spend a lot of money every year on replacing impellers and flaps. Therefore, there is an urgent need to create a more reasonable structure of the flotation machine. Recently, the Soviet Union conducted two experiments on flotation machines and achieved some results.
