Flotation Machine /  Sand flotation machine / Ore Flotation Machine
 

 
The introduction of flotation machine:

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.


Working principle of flotation machine :

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-mix with air. The remained slurry flows to the next trough until becomes residue.
