Flotation cell machine has the advantages of large air-absorption capacity and low energy consumption. Every cell owns three functions: air absorption, slurry absorption, and floatation 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.
Working Principle
1. when flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers
2. Meanwhile, the low pressure air send by fan is sent to this area through the air distributor in the hollow shaft
3. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough
4. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth through from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remis with air
5. The remained slurry flows to the next trough until becomes residue
