SF flotation machine is used for the separation of the nonferrous metals, black metals, precious metals, non-metal ore and industrial chemicals as well as other useful ore. It has the following features: large air inhalation and lower energy consumption. Every cell has air inhaled, pulp sucked and flotation three functions; a closed flotation circuit and no need any auxiliary machine. Horizontal placing is good for the change of the flow sheet and reasonable cycling of the pulp, besides, reducing the sand settlement to the least. It has the self-controlling device for the pulp and easy to adjust. Impeller has the backward blades so the upper blades bring the cocycle and under blades bring the circular.Structural feature:This machine is mainly composed of motor, upper and lower pump, cell, stator, rotor, mineral supply box, flashboard box, scraping plate, etc. The pump part is mainly composed of upper pump, lower pump, pulley, upper cover, lower cover, upper oil retaining ring, lower oil retaining ring, etc.Wearing parts:Bearing, stator, rotator ,main shaft V-belt and scrapper V-beltSF Flotation Machine is a new type of flotation equipment that has the double function of absorbing slurry and self-sucked air. It uses the backward double-blade curved novel impeller. The structure is reasonable, operation is reliable, and the performance of this flotation machine superior other flotation machine that has the slurry absorbing function. This series of flotation machine is suitable for sorting not only colored black metal, but also non-metallic such as coal, fluorspar, talc sorting. It can be used to separate non-ferrous metal, ferrous metal, noble metal, non-metallic mine, chemical material. It can be used in roughing, scavenging, selection or reverse flotation. In the flotation process, after being mixed with drug, some qualified mineral attaches on bubble, floats on the surface of slurry and is scraped out, other mineral still stays in the slurry, so the separating...
