Flotation machine is widely used for roughing, concentrating and reverse flotation of nonferrous metals that include copper, lead, zinc, nickel and molybdenum, ferrous metal and nonmetallic minerals.

Floatation machine feature of structure:
1.Two-sided vanes with back rake of the impeller ensures double circulating of slurry inside the tank.
2.The clearance between the impeller and cover board is big with large amount of air suction.
3.Low circle velocity of impeller; long service life of the brittle unit.
4.Front raked tank, small dead angle, rapid foam moving speed.
5.Performance features
    Big amount of suction air, small energy consumption.
    Long service life of the brittle unit.
    Better for the floatation of coarse ore.
Working Principle:
1. After intensively mixed, the pulp and medicaments are fed to the groove bottom of the first tank.
2. When the impeller of the flotation machine begins to rotate, negative pressure is formed, making the air and pulps at the bottom and middle part of the tank enter the mixing zone. The pulp, air and medicaments are then mixed in the mixing zone.
3. As a result of the centrifugal force, the blended pulps are lead to the mineralization area. The air is in full contact with the coal particle and forms mineralized bubbles which are then equally distributed to groove wall and removed upward to the separation region. These bubbles then gather as a foam layer and are discharged by the scraping tool. Finally, clean coal foam is produced by this flotation machine.
4. Coal particles that are not mineralized will be remixed, re-mineralized and re-separate through the recycle hole and the upper intake.
5. The left pulp that are not sucked by the impeller enters into the third tank after going through the process of first tank Thus, flotation machine runs in cycle and discharges ore pulp through the tailing box of the floatation machine.
