FLOTATION MACHINE

Flotation machine is the first mechanical open type machine to incorporate a vertical circulation of pulp, made possible by combining a “recirculation well” with the distinctive top feed impeller. This arrangement provides positive vertical circulation of pulp similar to the action in a propeller agitator. Pulp from an intermediate zone of the cell is circulated down into the eye of the impeller, mixed with air, and diffused out over the entire bottom of the cell, creating a uniform upward current. This principle varies from most other mechanical open type cells which circulate pulp by lifting it up from the bottom of the cell into the centre of a rotating element.

1. Large inhaling capacity and low energy consumption;
2. Complete flotation circuit with inhaling air and pulp, no auxiliaries are needed;
3. Process is easy to be changed;
4. Reasonable circulation of pulp decreases coarse sand sedimentation;
5. Automatic controlling device makes adjustment more convenient. The impeller is rotated by V-belt of motor and produces centrifugal effect with negative pressure. Enough air is inhaled into mixed pulp, and pulp mixes with drug at the same time. Mineral sticks on bubble completely and floats on the surface of pulp to form mineralized bubble. Useful bubble is scraped out by adjusting flashboard height and controlling liquid surfac.
