FLOTATING
JJF Floatation Cell (Based on American Weimco Design)
Principle
The rotation of impeller produces the eddy in vertical tube and draft
tube that forms the negative pressure, and the air is absorbed from
the air inlet pipe, mixing with the ore slurry from draft tube in the im-
peller and stator area. The motion of slurry-gas mixing flow generated
by impeller is along the tangential direction, and then it is converted
to radial motion under the effect of stator, and evenly distributed in
flotation cell. Mineral laden bubbles will rise to the foam layer, and
become foam products by the scraper.
Features
Shallow tank type, small impeller diameter, low rotating speed and
low power consumption;
The clearance between impeller and stator is big, and the stator is a
cylinder with oval hole, which makes for the mixture and dispersion of air and ore slurry;
The stator is lower than the impeller, which makes large circulating amount of ore slurry that is 2.5 times that of ordi-
nary flotation cell;

海
Umbrella-shaped scattered cover with hole can separate the eddy produced by impeller from foam layer in order to
keep the ore slurry surface stable;
Large circulating amount of ore slurry that is 2.5 times that of ordinary flotation cell makes for the mineralization of air,
medicament and ore;
Large amount of air suction and good effect of dispersion;
Proper stir intensity, good effect of solid particle suspension, no sediment and no need of discharge when stopping;
Wide range of processible particle size and high recovery rate of mineral dressing.

Special Tips
Mechanical stirring, automatic air but no ore slurry suction, and ladder in necessity during operation (Drop height:
300mm - 400mm);
It can be combined with SF flotation cell as a set of flotation cells, in which SF one serves as a suction tank and JJF one
serves as a direct flow tank.
Application
JJF floatation cell can be widely used in the mineral classifications of non-ferrous metals, black metals, and non-metals.
It is suitable for roughing and scavenging in large and medium flotation plant.
