The slurry is fed into the impeller by the feed pipe, and the centrifugal force generated by the rotating impeller is thrown into the groove, so that a negative pressure is formed under the cover plate, and the air is automatically taken in by the intake pipe. The inhaled air and the fed slurry are mixed together in the upper part of the impeller and thrown into the tank, thus generating a negative pressure and sucking in the air, thus continuously. In the drug-producing pulp, the floating mineral is carried by the bubble to the surface to form a mineralized foam layer, which is scraped off by the scraper to obtain a concentrate. The minerals and gangues that do not float up enter the intermediate chamber through the gates on the side walls of the trough and are fed into the next flotation tank. The adjustment of the slurry level in each or several tanks can be accomplished by adjusting the gates. This is how the slurry flows in the machine.
