Brief Introduction. When flotation machine works, slurry is inhaled from the bottom of the cell to the space between impellers. Meanwhile, the lowpressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole cell.
