Flotation Machine Working Principle from topgoldenmachine's blog

Flotation Machineis mainly used for sorting non-ferrous metals such as copper, zinc, lead, nickel, gold, etc. It can also be used for rough selection and selection of ferrous metals and non-metals. The sorter is driven by the motor V-belt drive to rotate the impeller to generate centrifugal force to form negative pressure. On the one hand, it inhales enough air to mix with the pulp. On the other hand, the slurry is mixed with the drug and the foam is refined to make the mineral bonded foam float. To the pulp surface again formed mineralized foam. Adjust the height of the gate and control the liquid level so that the useful foam is scraped by the scraper.

The coal slurry and the chemical agent are fully mixed and fed to the bottom of the first chamber of the flotation machine. After the impeller rotates, a negative pressure is formed in the wheel cavity, so that the slurry in the bottom of the tank and in the tank is respectively entered by the lower suction port and the upper suction port of the impeller. The mixing zone also allows air to enter the mixing zone along the air guide sleeve where the slurry, air, and medicament are mixed. Under the action of the centrifugal force of the impeller, the mixed pulp enters the mineralization zone. The air forms bubbles.

When the sorting chamber enters the floating area, the selected material is given 6 sorting points via the pulp distributor. The weak magnetic particles are sucked on the tooth plate and rotate with the sorting ring. The non-magnetic mineral particles pass through the gap of the tooth plate under the action of gravity and pulp flow, and are discharged into the tailings tank in the lower part of the sorting ring. When the sorting room is transferred to the position for cleaning in the mine, a small amount of clean water is fed in, and the gangue, contiguous body and slime mixed in are washed into the tailings tank (this machine is not provided with a middle ore tank) to improve the quality of the concentrate. the goal of. When the sorting chamber is switched to a weak magnetic field (concentrate flushing zone), pressurized water is sprayed and the weak magnetic mineral particles sucked on the tooth plate are flushed into the concentrate pit. The sorting chamber was then transferred to another magnetic field of opposite polarity, with each cycle of the sorting ring, and each sorting chamber was repeated six times.

Un-mineralized coal particles above the bottom of the tank will be mixed, mineralized and separated again through the circulation holes and the upper suction port. Some of the pulp that has not been inhaled by the impeller under the tank passes through the middle ore box buried in the slurry and enters the bottom of the tank in the second chamber. After completing the entire process of the first chamber, it enters the third chamber. The flotation machine is cycled and the slurry is passed through the end. After entering the tailings tank in one chamber, the final tailings were discharged.
