SF-Flotation-Cell

SF Flotation Cell

【Introduction】:
SF flotation cell is a mechanical agitation type flotation machine with self-slurry suction and self-air suction
【Volume】:
0.37~20m3
【Improvement】:
Both sides of the impeller with back rake blades ensures double circulating of slurry inside the flotation tank. Forward type tank, small dead end, fast foam movement

【Advantages】

Large air suction volume, low power consumption;

Long service life of wear parts Each tank with air suction, slurry suction and flotation function does not need any accessory equipment to form flotation circle, which is convenient for process flow changing;

The reasonable slurry circulation minimizes coarse sand sediments, and is conducive to flotation of coarse particle;

Auto-control device of slurry volume, convenient adjustment ;

Impeller with backward style upper and lower leaf, the upper blade generates upper circulation; the lower blade generates lower circulation.
Mechanical stirring, self- air suction, self-slurry suction;

SF flotation cell is composed flotation cell unit with JJF flotation cell as the suction tank of every operation.

【Product Structure】

The working principle of SF flotation cell: When the impeller rotates, the pulp in the upper and lower impeller cavities generates centrifugal force under the action of the upper and lower blades and is thrown to the four sides, forming a negative pressure zone in the upper and lower impeller cavities. At the same time, the pulp on the upper part of the cover plate is inhaled into the upper impeller cavity through the circulation hole on the cover plate, forming an upcycling of the pulp. When the lower blade throws the pulp around, the lower pulp adds to the center, thus forming the lower cycle of the pulp. The air is sucked into the upper impeller chamber through the suction tube and the central tube, and mixed with the pulp to form many fine bubbles. After steady flow through the cover plate, the air is evenly dispersed in the tank to form mineralized bubbles. The mineralized bubbles rise to the foam layer and are scraped out by the scraper.

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

【Successful case】

SF Flotation Cell

A copper dressing plant in Yunnan adopted gravity separation process firstly, but grade is low after separation. Finally the client consulted Xinhai through friends, and decided to adopt gravity - flotation separation process eventually after the mineral processing test. The flotation process adopted SF flotation cell which is researched and developed by Xinhai independently. Each tank with air suction, slurry suction and flotation function does not need any accessory equipment to form flotation circle, which is convenient for process flow changing and improves the separation efficiency. After separated, the concentrate grade is increased by 10% than expected, the economic benefit is guaranteed.
