Flotation Equipment
SF Type Mechanical Agitation Flotation Machine
The SF is a mechanical agitation flotation machine that draws in air through its impeller, keeping solids suspended. It needs no external blower, so circuit design is simple. It functions in rougher, scavenger, and cleaner stages for base metals, precious metals, and industrial minerals.
Technical parameters
Tank shape and impeller speed jointly produce a stable froth and promote effective bubble-particle attachment. The machine suits conventional tank-cell geometry and fits well into existing plant layouts.
The table lists eleven SF models from small pilot-scale cells to larger production units. Effective volume and motor power increase with model size, and the single-tank weight rises correspondingly. Use the processing capacity column to match your required volumetric feed rate. Always confirm that the dimensions fit the available floor space in the flotation bay.

Standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Use them to shortlist, then confirm the duty by testwork, flowsheet calculation and a written confirmation from the manufacturer.
What decides the selection
Before selecting an SF model, define the feed solids content, particle size distribution, and target volumetric throughput. The number of cells in series depends on the required retention time and circuit configuration. Confirm whether the ore needs a rougher, scavenger, or cleaner stage, as froth characteristics and power input requirements vary with duty.
