SF-2.8 SF-4 Self Aspirating Flotation Machine for Large Ore Beneficiation The SF-2.8 and SF-4 are the larger models of the SF series, engineered for high-throughput ore beneficiation with 2.8–4 m³ cells. They deliver self-aspirating operation at production scale, so large plants get the simplicity of the SF design without sacrificing capacity. Big cells, strong output. 2.8–4 m³ volumes suit high-tonnage circuits. Self-aspirating. Air and pulp are drawn in automatically in a
