Working Principle of 5 Types Of Flotation Machines
After the pulp and flotation reagent are fully mixed, they are sent to the flotation column through the central feeding device. The pulp is slowly descended under the action of gravity, and the compressed air is dispersed into a large number of tiny bubbles through the inflator, which are evenly distributed on the entire section of the …
