SF Flotation Cell
Principle
When the impeller rotates, the centrifugal force with the action of upper and lower vanes is produced, and drives the slurry in upper and lower wheel chambers thrown around, by which the negative pressure area is formed in upper and lower wheel chamber. At the same time, the slurry on top of cover plate is absorbed into upper wheel chamber to form upper circulation via the circular hole on the cover plate. When the slurry is thrown around by the lower vane, the lower slurry flows to the center to complement, by which the lower circulation is formed. And the air is sucked into the upper impeller chamber via suction pipe and center cyl-inder, mixing with absorbed slurry, and forming a large number of tiny air bubbles. After steady flow through the cover board, these bubbles are evenly dispersed in tank, forming mineral laden bubbles. Then mineral laden bubbles will rise to the foam layer, and become foam products by the scraper.

Features
The impeller with backward-style two-sided vanes ensures double circulation of ore slurry in tank. Large clearance between impeller and cover plate ensures large amount of air suction. Low circular velocity of impeller ensures long service life of wear parts. Forward-style tank body with small dead angle ensures high speed of bubble motion. Large amount of air suction and low energy consumption. Long service life of wear parts. Better for the flotation of coarse-grained minerals.
Application
SF mechanical agitation flotation cell can be widely used in the mineral classifications of non-ferrous metals, black met-als, and non-metals. It is suitable for roughing and scavenging in large and medium flotation plant.
