SF Floatation Cell
Principle
When the impeller rotates, the centrifugal force with the action of
upper and lower vanes is produced, and drives ore slurry in upper
and lower wheel chambers thrown around, by which the negative
pressure area is formed in upper and lower wheel chambers. At
the same time, the ore slurry on top of cover plate is absorbed
into upper wheel chamber to form upper circulation via the circu-
lar hole on the cover plate. When the ore slurry is thrown around
by the lower vane, the lower ore 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 cylinder, mixing with absorbed ore slurry, and forming a
large number of tiny air bubbles. After steady flow through the
cover board, these bubbles are evenly dispersed in tank, form-
ing 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.

Special Tips
Mechanical stirring, automatic air and ore slurry suction;
It can be combined with JJF flotation cell to be a set of flotation cells as suction tanks of each operation.
Application
SF 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.
