SF-Flotation Machine
1)Increase concentrate grade of 4-6%
2)Cycling rate up 8%
3)Increase the output by 12%
Mining Flotation machine is widely used for roughing, concentration and reverse flotation,
the reverse flotation are nonferrous metals that include copper, lead, zinc, nickel and molybdenum,
ferrous metal and nonmetallic minerals.
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, forming the air and pulps
at the bottom and middle part of the tank enter the mixing zone. Then the pulp, air and medicaments are mixed there.
3. Because of centrifugal force, the blended pulps are lead to the mineralization area.
The air are in full contact with the particles and forming mineralized bubbles which are 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. 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, enter 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 flotation machine.
