China SF flotation cell is widely used


    SF Flotation Cell adopts creative forward tank double side blades of water wheels draft tube and the false bottom device. The slurry in tank takes upper and lower circulation according to the fixed flow mode which is conducive to suspension of coarse particle.

    SF flotation cell is widely used for separating non-ferrous metal black metal noble metal non-metal mineral raw body and materials of chemical industry which are subject to roughing and scavenging of large and middle scale flotation plants.

    SF type floater machine is a mechanic mixing floater with double functions of self-absorption of air and slurry. It adopts forward-leaning tank and double-blade turbine of a new structure, coordinated with fluid duct and the false bottom device. The tank slurry has a double cycle of both above and below in a fixed flow manner, which contributes to the coarse mineral suspension. SF type floater is mainly composed of tank body, main drafts with impellers, motor, scraper and driving equipment. Those with a volume over 10m^3 are set with fluid duct and false bottom.

    When SF type Flotation Equipment is at work, the motor drives the main shaft through V belt to make the lower part of the impeller rotate. The main characteristics of this floater are demonstrated in the impeller. The impeller has a back-inclined double-sided blade, which can realize the double cycle of tank slurry. When the impeller rotates, driven by the upper and lower blades (i.e. main and auxiliary blades), the slurry in the upper and lower blade cavities generates centrifugal force and is thrown around to make the impeller cavity form a zone of negative pressure. At the same time, ore slurry on the upper part of the cover plate is sucked into the impeller cavity through the circular hole, forming an upper slurry circulation. However, the slurry thrown out of the impeller cavity is much greater than the three-phase mixture proportion thrown out by the upper blade and the centrifugal force is thus greater and velocity attenuation is slower. Moreover, it produces additional driving force to the three-phase mixture thrown out by the upper blade to increase its centrifugal force so as to improve the vacuum degree of the impeller cavity, which plays an auxiliary suction effect. When the lower blade throws out slurry around, its lower slurry will gather in the center, thus forming a lower cycle of slurry. The air is sucked into the upper impeller cavity through the suction pipe and the center cylinder to mix with the sucked slurry and form a large number of small foams. After the flow is stabilized through the cover plate, it is uniformly dispersed in the tank, forming mineralized foams. Mineralized foams float up to the foam layer, which form the foam products through the scraper.
