This type of flotation machine is formed by U through solid, hollow shaft inflation, suspension rotor and new type impeller. The cone impeller lean backwards, the blending quantity is big and the pressure head is small, the advantages are: simple structure and low energy consumption. Inside the impeller, there is air distributor, which distributes air into most parts of impeller evenly.
When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low_pressure 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 trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the re-mis with air. The remained slurry flows to the next trough until becomes residue.
