The impeller of S F flotation machine has a backward tilting double-sided blade, which can achieve double circulation of slurry in the tank. The gap between the floatation machine and the cover plate is larger, and the suction volume is less affected when wearing. Horizontal arrangement does not require foam pump; impeller circumferential speed is low, impeller cover plate life is long, slurry is fixed up and down double circulation in a fixed way, which is conducive to coarse mineral suspension.
KYF flotation machine adopts U-shaped tank, hollow shaft aeration and suspended stator, especially a new impeller. It is a kind of conical impeller with blades tilted backward at an angle, similar to centrifugal pump with high specific speed. It has the advantages of large amount of slurry, small head, low power consumption and simple structure. A porous cylindrical air distributor is also installed in the impeller cavity, which makes the air evenly distributed in most areas of the impeller blades in advance and provides a large slurry air contact interface.
