JJF Floatation Cell, Wemco Floatation
Floatation Cell— Introduction
A self-air suction mechanical stirring floatation cell without slurry suction (Referring to the design of USA wemco flotation machine)
Floatation Cell— Effective Volume
4~20m3
Floatation Cell— 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.
Floatation Cell— Advantages
Large pulp circulation volume up to 2.5 times, is conducive to mineralization of pulp, reagents and air
Large air suction volume, good dispersion effect
Reasonable circulation of mineral slurry and the solid particles suspend well, no sediment in tank, and no need to feed mine when it stopped.
Wide range of particle size and high recovery rate of ore selection
Mechanical agitation; Self-air suction but not slurry; Ladder is necessary during processing (drop height: 300-400 mm)
It can be combined with model SF as a flotation cells set: Model SF as the suction cell and model JJF as the direct flow cell.
Floatation Cell— Work Principle
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.
Floatation Cell— Product Structure
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.
