A self-air suction mechanical stirring floatation cell without slurry suction (Referring to the design of USA wemco flotation machine)
Production capacity: 4～20m3
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.
JJF type flotation machine is mainly composed of tank body, impeller, stator, dispersing cover, false low, draft tube, vertical tube, adjusting ring. Shallow tank, small diameter, low rotary speed, and low power consumption. Large clearance between impeller and stator, the stator is a cylinder with elliptic hole, and it is good for mixing and dispersing the gas and pulp. The height of stator is lower than impeller, pulp circulation volume is large, and it can be reached at 2.5 times of others. The umbrella-type dispersion cover with holes of the stator can separate the eddy current and bubbles that produced by impeller, so as to keep the pulp surface stable. Flotation cell is widely used for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to roughing and scavenging of large and middle scale floatation plants.
