Flotation Machine can be used to separate nonferrous metal, ferrous metal, heavy metal, nonmetallic mine, chemical material such as gold, copper and recycling minerals. Each chute can inhale gas, sink magma, separate. No assisting equipment are required,and Flotation Machine must be levelly installed. Flotation Machine is easy to change the flow chart. The cycling way of magma is very reasonable. Flotation Machine can reduce the impurities to a great extent. There is automatic equipment on the magma surface, easy to adjust. The impeller also owns the upper and lower retroversion blade. The upper one makes the magma cycle upward, while the lower one makes the magma cycle downward.

Working principle of Flotation machine
The impellers are driven through V belt transmission, which brings centrifugal effect to form the negative pressure. On the one hand, the flotation machine inhales sufficient air to mix with ore slurry; on the other hand it stirs ore slurry and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board. Each chute can inhale gas, sink magma, separate. No assisting equipments are required, and it must be levelly installed. It is easy to change the flow chart. The cycling way of magma is very reasonable. It can reduce the impurities to a great extent. There is automatic equipment on the magma surface, easy to adjust. The impeller also owns the upper and lower retroversion blade. The upper one makes the magma cycle upward, while the lower one makes the magma cycle downward.

Flotation Machine features:
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.
