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 column and rise slowly.

Laboratory Flotation Test Machine

Each cell of the flotation machine contains an impeller, which is a rotating device responsible for stirring the slurry. The impeller creates a turbulent environment in the cell, ensuring thorough mixing of the reagents and ore particles. Air Supply. Air is introduced into the flotation cell through various mechanisms, such as blowers or spargers.

Flotation

Basic flotation variables and attainable recovery/grade levels of valuable components are analysed with laboratory tests. This information is then used to design larger-scale tests, either for a minipilot or a pilot test run. Flotation machines with cell size from 1.5 to 15 litres are used in the laboratory testing.
