When the impeller rotates, the pulp in the impeller cavity generates centrifugal force under the action of the impeller.
The pulp is thrown around by the centrifugal force, creating a negative pressure zone in the impeller cavity.
Air is sucked into the impeller cavity through the suction pipe and the central cylinder and mixed with the sucked pulp.
After mixing, a large number of fine air bubbles are formed, which, after passing through the cover plate to stabilise the flow, are evenly dispersed
in the tank to form mineralised bubbles.
The mineralised bubbles float up to the froth layer and are scraped out by the scraper to form the froth product.
