【Introduction】:A bar flotation cell with self-air suction and mechanical agitation
【Capacity】: 1～4m3
【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.
Strong agitation force; nice moving trace of slurry; suitable for the selection of coarse ore with bigger gravity and high sedimentation rate
Uniform mixing of slurry, air and reagents
Rapid flotation speed
Easy to restart after stopping
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.

A copper ore dressing plant in Anhui chose Xinhai EPC service. In the flotation process, considered the ore proportion is much big, and the granularity is coarser, Xinhai designed and updated XJB bar flotation cell for it, adopted high manganese steel-casting steel bar, the wear-resisting performance is greatly improved, solving the low durability of previous bar type flotation equipment. In flotation process, the capacity is up to 3000 t/d, and the energy costs are relatively low.
