A bar flotation cell with self-air suction and mechanical agitation.Production capacity:1～4 m3.Product Improvement: There is a convex bench and an arc-shaped steady flow plate. The convex bench works as the guide groove, which makes the mixture of air and slurry rush to the bottom of tank. And then with the steady flow plate the mixture spreads in the tank uniformly, moving in the shape of W.
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.
