Function of flotation machine impeller:
1.When the pulp is push out by impeller, form a negative pressure suction under the coverplate;
2. Regulate the amount of pulp into the impeller;
3. Avoid during downtime, ore pressure impeller and difficult to start;
4. Some steady flow function. When flotation machine work, the feed tube feed the slurry to the center of coverplate, the impeller rotating centrifugal force generated the pulp out, at the same time form a negative pressure between the impeller and the cover plate, and the intake pipe automatically inhale the outside air. Strong stirring impeller function make the pulp is mixed with air fully, and will be divided into many small bubbles.Moreover, in the rear of the impeller blade will precipitate some air bubbles from the pulp.

Application:
Flotation is a selective process and can be used to achieve specific separations from complex ores such as lead-zinc, copper-zinc, etc. Initially developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expanded to include the oxidized minerals, non-metallic ores and fine coal.
