SF Mechanical Flotation Equipment With Large Air Intake Low Energy Consumption
The SF flotation machine is a mechanical flotation machine designed for mineral processing and ore beneficiation. It combines self-aspirating air and slurry suction with mechanical flotation, providing a large air intake while maintaining relatively low energy consumption.
The SF design uses a backward-inclined double-blade impeller and horizontal cell configuration, making it suitable for ferrous, non-ferrous and non-metallic mineral separation.
- Large air intake for flotation operation
- Low energy consumption
- Self-aspirating air and slurry suction
- Backward-inclined double-blade impeller
- Horizontal flotation machine configuration
- No separate froth pump required
- Low impeller peripheral speed
- Helps extend wear-part service life
- Suitable for ferrous, non-ferrous and non-metallic minerals
During operation, the rotating impeller creates negative pressure in the impeller chamber. Air enters through the air pipe and center tube, while slurry enters through the corresponding circulation passages.
The air and slurry are mixed by the rotating impeller and then dispersed into the flotation cell to form mineralized bubbles. Valuable mineral particles attach to the bubbles and rise to the froth layer for recovery. SF型浮选机使用说明书---修改后
The SF flotation machine uses a backward-inclined double-blade impeller.
Its design provides air and slurry suction while maintaining stable movement of the pulp inside the flotation cell. The relatively low impeller peripheral speed also helps reduce wear on the impeller and other wearing components.
The SF flotation machine can be used in mineral flotation circuits for:
- Mineral processing
- Ore beneficiation
- Ferrous mineral flotation
- Non-ferrous mineral flotation
- Non-metallic mineral flotation
- Froth flotation circuits
- Roughing, cleaning and other flotation operations
The SF series is suitable for mineral separation involving ferrous, non-ferrous and non-metallic minerals.

The SF flotation machine combines large air intake and low energy consumption with self-aspirating air and slurry suction. Its horizontal configuration eliminates the need for a separate froth pump, while the low-speed impeller design helps reduce wear on flotation components.
1. What is the main advantage of the SF flotation machine?
Its main advantages include large air intake, low energy consumption, self-aspirating air and slurry suction.
2. Does the SF flotation machine require an external air blower?
The SF series uses self-aspirating air rather than requiring an external air supply system.
3. Does the SF flotation machine require a froth pump?
No. Its horizontal configuration does not require a separate froth pump.
4. How is the SF flotation machine selected?
Selection should consider the required capacity, effective cell volume, mineral characteristics and flotation test results.
The flotation cell quantity, configuration, scraper arrangement, feed/intermediate/tailing boxes and overflow gate control can be specified according to the flotation process and installation requirements.
