Product Introduction

The SF Flotation Cell is a mechanical agitation flotation machine with both slurry suction and air suction capabilities. As a third‑generation flotation device, it is widely used for roughing, scavenging, and concentration of nonferrous metals, ferrous metals, and non‑metallic minerals.

With a capacity range of 0.2–20 m³/min, simple structure, stable operation, and strong adaptability, it is particularly suitable for small and medium‑sized mineral processing plants as well as complex mineral separation processes.

Flotation Cells / Machine Types

Agitating flotation machine

Self‑priming flotation machine

Aeration flotation machine

Flotation column machine

Available models include SF, XJK, JJF, XCF, KYF, suitable for various mineral flotation operations worldwide.

Key Advantages

Large air suction volume and low power consumption

Long service life of wear parts

No need for auxiliary equipment to form flotation circulation

Efficient slurry circulation with reduced coarse sand sedimentation

Auto-control device for slurry volume adjustment

Backward upper and lower impeller blades for dual circulation

Mechanical stirring with self-air and self-slurry suction

Can be combined with JJF flotation cell for matched suction operations

Advanced Performance Features

Self-Priming Structure

Special impeller–stator assembly eliminates the need for a blower

Reduces equipment investment by 20%–30%

Air intake capacity reaches 1.0–1.5 m³/(m²·min)

Optimized Slurry Circulation

U-shaped trough design with guide plates

Prevents sedimentation and improves slurry suspension

Ideal for slurry concentrations of 20%–45%

Excellent for fine mineral particles below 0.074 mm

Energy-Saving & High-Efficiency

Energy consumption reduced by 15%–20% compared to A-type machines

Power consumption for dry ore: 1.8–2.5 kW·h/t

Wide gap between impeller and cover for improved air dispersion

Flexible Adaptability

Integrates seamlessly with JJF flotation cells

Suitable for minerals including copper, lead, zinc, gold, pyrite, graphite, fluorite, and more

Ideal for coarse and fine particle flotation projects

Applications

SF flotation cells are widely applied in:

Nonferrous metal beneficiation

Ferrous metal beneficiation

Gold, copper, and lead–zinc flotation circuits

Graphite and fluorite flotation processing

Medium-small mining plants with complex mineral separations

Dasen SF flotation cells have been successfully installed in mineral processing plants domestically and abroad.
