Froth Floatation Machine

Working principle Froth Flotation Machine
After intensively mixed, the pulp and medicaments are fed to the groove bottom of the first tank.
When the impeller of the froth 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.
As a result of the cenrifugal force, the blended pulps are lead to the mineralization area. The air is in full contact with the coal particle and forms mineralized discharged by the scraping tool. Finally, clean coal foam is produced by this flotation machine.
Advantages of Froth Flotation Machine
It increase concentrate grade by 4-6%.
It increase cycling rate by 8%.
It increase production by 12%.
Application of Froth Flotation Machine
Froth flotation machine is widely used for roughing, concentrating and counter-flotation of nonferrous metal that includes copper, lead, zinc, nickel and molybdenum, ferrous metal and nonmetallic mineral.
