A semi-autogenous or ball mill then grinds and crushes the ore to a finer particle size, which is then fed to a trommel screen. Cyclones are then employed to separate correctly-sized particles from oversized particles, with oversized particles being returned to the mill for further crushing.
The flow sheet (Figure 10) includes a primary crusher / S / Ball mill comminution circuit to achieve a grind size of P 80 180µm, a natural pH flotation circuit, rougher flotation with a regrind circuit to achieve a grind size of P 80 90µm and a cleaner flotation . More
It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC). This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of 'critical size' material in the circuit.
semi autogenous ball mill crushing flow sheet.

Traditionally, the process selection choice was between a conventional, well-tried, three-stage crushing circuit followed by ball-milling, or single-stage crushing followed by a Semi-Autogenous (SAG) mill and ball mill. The latter is preferred for wet sticky ores to minimize transfer point chute blockages etc, and can offer savings in both ...
The semi-autogenous mill is a new type of grinding equipment with both crushing and grinding functions. It has the advantages of simple process flow, small investment, short construction cycle, and easy operation. It can directly grind raw materials or coarsely crushed materials to 0.074mm. The grinding ratio can reach 4000-5000, which is ten ...
