3. Stable & Durable Operation

Solid structural design ensures steady long-term running, with a low failure rate.

4. Cost-effective & Easy Maintenance

Compact layout, simple daily upkeep, cuts overall production cost.

Working Principle

 

The SF-type flotation machine uses an electric motor to drive the impeller to rotate at high speed, creating a negative pressure zone within the impeller cavity, thus achieving self-aspiration and self-slurry intake. The slurry enters the mixing zone from the bottom and middle of the tank through the upper and lower suction ports of the impeller. Simultaneously, air is drawn into the upper impeller cavity through the suction pipe and the central cylinder, thoroughly mixing with the slurry to form numerous fine bubbles. Under the action of the stator and turbulence plates, the bubbles are uniformly dispersed across the tank cross-section, and mineral particles selectively adhere to the bubble surface, forming mineralized bubbles that float to the froth layer and are scraped off by the scraper to become the concentrate product. The unmineralized slurry then enters the next tank for further processing through the circulation holes or the middlings box, achieving multi-stage continuous flotation.

Product Structure

 

The SF-type flotation machine mainly consists of the following components:

Tank: Forward-inclined U-shaped or stepped design to reduce dead zones and promote slurry circulation.

Impeller and Main Shaft: Impeller with backward-inclined double-sided blades to achieve dual circulation of slurry; the main shaft connects to the motor drive system.

Cover Plate and Guide Device: Works in conjunction with the impeller to stabilize the flow and guide the slurry flow.

Motor and Drive System: Typically uses a V-belt drive to drive the impeller.

Scraper Device: Used to scrape frothy concentrate; can be configured on one or both sides.

False Bottom and Guide Pipe (equipped when volume > 10m³): Optimizes the internal flow field and improves separation efficiency.
