The SF flotation cell is a mechanical flotation machine designed for mineral processing and ore beneficiation. Its backward-inclined double-blade impeller promotes continuous slurry circulation inside the flotation cell, helping maintain solid particles in suspension during flotation.
The auxiliary blades promote circulation in the lower part of the cell, supporting coarse mineral particle suspension and helping reduce settling. The SF design is suitable for ferrous, non-ferrous and non-metallic mineral flotation.
When the impeller rotates, a negative-pressure zone is created inside the impeller chamber. Air enters through the air pipe and center tube, while slurry is drawn into the impeller chamber through the center tube and circulation openings.
The air and slurry are mixed in the impeller chamber and then discharged through the impeller and cover plate. The mixture is dispersed into the flotation cell to form mineralized bubbles for froth flotation and mineral separation.
The SF flotation machine uses a backward-inclined double-blade impeller consisting of main and auxiliary blades.
The main blades assist air and slurry suction, while the auxiliary blades promote lower-cell slurry circulation and increase the distance between the impeller and tank bottom, helping reduce coarse sand settling.
The SF flotation machine can be used in mineral flotation circuits for:
The machine configuration and number of cells can be selected according to the flotation process and required total volume.
| Model | Effective Volume (m³) | Capacity (m³/min) | Air Intake (m³/m²·min) | Main Motor Power (kW) | Impeller Speed (r/min) | Scraper Speed (r/min) | Weight (kg) |
|---|---|---|---|---|---|---|---|
| SF-0.37 | 0.37 | 0.2–0.4 | 0.8–1.0 | 1.5 | 352–442 | 17 | 468 |

The SF flotation machine integrates air intake and slurry suction into the flotation process, reducing the need for additional slurry or froth pumping equipment. Its horizontal arrangement and internal slurry circulation make it suitable for mineral processing plants requiring a self-aspirating flotation cell.
For equipment selection, the required ore type, slurry capacity, flotation process, cell volume and number of cells should be considered together.
1. What is an SF flotation machine?
SF is a self-aspirating mechanical flotation machine with both air suction and slurry suction functions.
2. Does the SF flotation cell need a froth pump?
No. The SF flotation machine is designed for horizontal operation without a separate froth pump.
3. What minerals can the SF flotation machine process?
It is designed for the separation of ferrous, non-ferrous and non-metallic minerals.
4. How do I select the right SF flotation cell?
Selection should consider the ore type, required slurry capacity, effective cell volume, flotation process and required number of cells.
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.
