Introduction of mineral dressing equipment                                                                       

Mineral Dressing Production Line can be used to separate non-ferrous metal, ferrous metal, noble metal, non-metallic mine, chemical material . It can be used in roughing, scavenging, selection or reverse flotation . In the flotation process, after being mixed with drug, some qualified mineral attaches on bubble, floats on the surface of slurry and is scraped out, other mineral still stays in the slurry, so the separating purpose is finished.

  Principle of mineral dressing equipment                                                                            

Mineral Dressing Production Line  is rotated by V-belt of motor and produces negative pressure by centrifugal function . Enough air is sucked to mix slurry, and slurry mixes drug at the same time . Mineral sticks on bubble completely and floats on the surface of slurry to form mineralized bubble . Useful bubble is scraped out by adjusting flashboard height and controlling liquid surface.

 Main processing of mineral dressing equipment:                                                                 

 1. Crushing and grinding stage: The extracted ore should be primarily crushed by jaw crusher through the vibrating feeder and then secondly crushed by fine crusher.

When it gets the reasonable fineness, it is transported into ball mill by elevating conveyer and feeder, at last, it is milled by ball mill.

2. Classifying stage: The subtle milled ore gets the next procedure: classification. There is a theory that if the weights of solid particles are different, the sedimentations will be different, and the mixed ore can be classified by screw classifier. 

3. Mixing and Floatation stage: The classified ore gets into mixing tank for fully mixing. At this stage, chemical agent for foam can be added. After fully mixing, the slurry will enter into flotation machine.

When the floatation 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, 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.

4. Concentrator thickening and drying stage: Then fluorspar ore is separated from others. Because the separated ore are wet, they should be dewatered by thicker initially, and dried by dryer.
