Self-Aspirated Mechanical Flotation Machine for Ore Processing The BF Flotation Machine is a self-aspirated and self-pulping mechanical flotation machine designed for mineral processing applications. Developed as an improved version of the SF flotation machine, BF uses a closed double-cone impeller to generate strong downward pulp circulation while drawing air into the impeller chamber. The BF flotation machine combines air suction, pulp suction and flotation functions in the
