Working principle of coal flotation machine
The pretreated slurry is fed to the false bottom of the first chamber of the flotation machine, and the negative pressure formed by the rotation of the impeller in the wheel chamber causes the slurry under the false bottom and in the tank to enter the mixing zone through the lower and upper suction ports of the impeller, respectively.
This also allows air to enter the mixing zone along the air guide sleeve, where the slurry, air, and reagents are mixed. Under the centrifugal force of the impeller, the mixed slurry enters the mineralization area, and the inhaled air is sheared to form bubbles and crushed.
It contacts with the coal particles to form mineralization bubbles. Under the action of the stator and turbulence plate, it is evenly distributed on the section of the tank body, and moves upward into the separation area to form a foam layer that is enriched and discharged by the foam scraping mechanism to form a cleaned coal foam.
The unmineralized coal particles on the false bottom will be sucked into the impeller through the circulation hole and upper suction port, and then mixed, mineralized, and separated again. The portion of the ore slurry that has not been mineralized in a timely manner inside the tank enters the false bottom of the second chamber through the middle ore box buried in the slurry, just like the entire process completed in the first chamber before entering the third chamber.
This cycle continues, and the ore slurry passes through the last chamber and then enters the tailings tank to discharge the tailings.
