Stirring
The slurry is fed to the false bottom of the first chamber of the flotation machine, and the impeller rotates in the wheel chamber to form a negative pressure, which makes the slurry in the false bottom and the slurry in the tank enter the mixing area from the lower and upper suction ports of the impeller respectively, and also makes the air and the reagent enter the mixing area along the air guide sleeve, where the slurry, air and reagent are mixed. Under the centrifugal force of the impeller, the mixed ore enters the mineralized area, the air is cut to form bubbles and comminuted, and is fully contacted with the coal particles, forming the mineralized bubble. Under the action of the stator and the steady flow plate, it distributes evenly in the cross section of the tank and moves upward into the separation area, enriching the foam layer and discharging it from the scraping mechanism to form the clean coal foam. Coal particles that are not mineralized on the false bottom will be sucked into the impeller through the circulating hole and the upper suction port, and then mixed, mineralized and separated again. Part of the pulp which is not mineralized in time in the tank enters the false bottom of the second chamber through the middle ore box buried in the pulp, just like the whole process completed in the first chamber, enters the third chamber, so that the pulp enters the tailings box after the last chamber and discharges the tailings.
