SFFlotation Machine

Description
SF flotation machine is used for the separation of the nonferrous metals, blackmetals, precious metals, non-metal ore and industrial chemicals as well asother useful ore. It has the following features: large air inhalation and lowerenergy consumption. Every cell has air inhaled, pulp sucked and flotation threefunctions; a closed flotation circuit and no need any auxiliary machine.Horizontal placing is good for the change of the flow sheet and reasonablecycling of the pulp, besides, reducing the sand settlement to the least. It hasthe self-controlling device for the pulp and easy to adjust. Impeller has thebackward blades so the upper blades bring the cocycle and under blades bringthe circular.

Structureand Material:
When the impeller is revolving, the pulp in the impeller cavity can be swingout at the centrifugal force by the impeller blades and be negative pressurezone in the impeller cavity. Meanwhile, the pulp in the top of the cover can beinhaled to the impeller cavity through the circulatory hoses on the cover andthen the pulp can be circulating upward. The pulp in the bottom of the impellercan be swing out and supplement to the center so it forms the circulatingdownward. Air is inhaled from the inhalation pipe and center pipe to impellercavity and mix with the pulp and then arise a lot of small bubbles. The bubblesgo through the cover and evenly disperse in the cells and form the mineralbubbles. Mineral bubbles float to the forth section and be scraped out to beforth product. 

StructureFeatures:
1 Two sides backward blades of the impeller make the pulp bicirculating in thecell.
2 Large space between impeller and cover can have large air inhalation.
3 Low rotation speed of impeller extends the service life of the spare parts.
4 Forward tank and blind angel make the forth moving quickly.

PerformanceFeatures:
1 Large air inhalation and low energy consumption.
2 Long life of the spare parts.
3 Good for the coarse particles flotation.

Note:
1 Mechanical agitation, self air inhalation and pulp suction.
2 It can be combined with JJF cells to be the suction cell.

Application:
It is widely used in enrichment for non-ferrous metals, black metals andnon-metals in medium and big flotation factories for the roughing andscavenging concentration.
