A self-air suction mechanical stirring floatation cell without slurry suction (Referring to the design of USA wemco flotation machine).Production capacity:4～20 m3.Product Improvement:Shallow groove, the stator lower than the impeller, large slurry circulation volume, low energy consumption; the stator is a cylinder with an elliptical hole which is conducive to the dispersion and mixing of pulp and air. Umbrella shaped dispersion cover with hole keeps the pulp surface stable.
When the flotation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.
