SF flotation machine

What is SF flotation machine?

SF flotation machine, also known as SF type mechanical agitation flotation machine, is a self-absorption, self-absorption pulp type mechanical agitation flotation equipment.

The impeller of SF type flotation machine has backward tilting double-sided blades, which can realize double circulation of pulp in the tank, large clearance between impeller and cover plate, large suction volume, and low circumferential speed of impeller, which makes long life of wearing parts. Forward tilting tank body, small dead angle, foam movement speed, which in turn improves the flotation efficiency and shortens the flotation time.

If you are a beginner and do not know about flotation machine, tell us your raw material characteristics, finished product requirements, site conditions, production budget, hourly production, and other requirements, we have professional engineers to equip you with a suitable model at a reasonable price. Next, let’s see the types of flotation machine we can supply.

What Is SF flotation machine Used For?

SF type flotation machine as a kind of mining flotation machine has the characteristics of large suction capacity and long life of wearing parts.SF type flotation machine is widely used in the flotation operation of nonferrous metals, black metals and nonmetals with obvious effect.

For example, A copper ore beneficiation plant in the beneficiation process only used the re-election method, after sorting the concentrate grade is low. By going to Chunlei Machinery for consultation and through the beneficiation test, the process was finally determined as heavy – flotation process. The SF type mechanical agitation flotation machine was used in the flotation, and the design of the forward tilting tank reduces the dead angle in the operation process, which makes the foam movement speed up and the sorting efficiency increase. After sorting, the concentrate taste was 10% higher than expected, and the subsequent economic benefits of the plant were greatly improved.

Applicable materials:It can be widely used in the separation of nonferrous metals, ferrous metals, and nonmetallic minerals, and is suitable for roughing and sweeping operations in large and medium-sized flotation plants.

Working Principle of SF Flotation Machine

When the impeller rotates, the slurry in the upper and lower impeller chambers is thrown around by the centrifugal force generated by the action of the upper and lower blades, forming a negative pressure zone in the upper and lower impeller chambers. At the same time, the slurry in the upper part of the cover plate is sucked into the upper impeller cavity through the circulating holes on the cover plate, forming the slurry upper circulation. When the lower impeller throws out the slurry in all directions, the slurry in its lower part replenishes to the center, thus forming the lower circulation of the slurry. And the air through the suction pipe, the center cylinder is sucked into the upper impeller cavity, and was sucked into the slurry mixing, the formation of a large number of small bubbles, through the cover plate flow stabilization, uniformly dispersed in the tank, the formation of mineralized air bubbles. Mineralized bubbles float up to the foam layer, scraped out by the scraper that is the foam product.

The structure of SF flotation machine is mainly composed of tank body, main parts with impeller, motor, scraper and transmission device, etc. Its volume is more than 10m3.

Advantageous features of SF Flotation Machine

• Impeller with backward tilting double-sided blades can realize double circulation of slurry in the tank.
• Large gap between impeller and cover plate, large suction volume.
• Low impeller circumferential speed, long service life of wearing parts.
• Forward tilting tank body, small dead angle, fast foam movement.
• Large suction volume, low energy consumption.
• Long service life of wearing parts.
• Favorable to the flotation of coarse-grained minerals.
• Mechanical agitation, self-absorption of gas, self-absorption of slurry.
• It can form a joint flotation unit with JJF-type mechanical stirring flotation machine as the suction tank for each operation.
