The motor drives the main shaft through a V-belt, rotating the impeller. The impeller features backward-inclined double-sided blades, creating dual slurry circulation in the tank. As the impeller rotates, slurry is sucked into the upper impeller chamber and mixed with air through the suction pipe, forming mineralized bubbles. These rise to the froth layer, which is scraped out as foam products.
