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.
Bar flotation cell has air inflation agitation group consisting of oblique rod wheel, convex plate, arc stabilizer, etc. Impeller is consisted of a disc and 12 bevel cone bars. The rotating speed of bevel cone bar gets faster and faster while downing and agitation force gets stronger accordingly.
