SF浮选机用于分离有色金属、黑色金属、贵金属、非金属矿物和化工原料、回收有用矿物。该设备吸气量大、功耗低。每槽兼有吸气、吸浆和浮选三重功能，自成浮选回路，不需任何辅助设备，水平配置，便于流程的变更。矿浆循环合理，能最大限度地减少粗砂沉淀。设有矿浆面的自控装置，调节方便。叶轮带有后倾式的上下叶片。上叶片产生矿浆上循环，下叶片产生矿浆下循环。

,slurry absorption,and flotation separation,and the cells form a floatation separation loop by itself without any auxiliary equipment,and is allocated horizontally,which favors the change of flow.The circulation of mineral slurry is reasonable,and can avoid the disposition of coarse sand to the largest extent.There is self-control device on the surface of mineral slurry,so it is easy to adjust it.The impeller has backward-inclined upper and lower vanes,which produce upper and lower circulation of mineral slurry respectively.
