Back Forty Mine Project | Aquila Resources | Operations

The ball mill is very similar to the SAG mill, except it has a larger proportion of steel balls to assist in the grinding process. The grinding process reduces the ore to a very fine grain size that is mixed with water to produce a slurry.

Ball mill

The SAG mill is located on a roller support system, for example as shown in FIG. 6, so that the SAG mill is rotated about the longitudinal axis of the cylinder. The feed system, e.g. a helix feeder as described above or a straight pipe, effects continuous feed of particulate ore into the cylindrical grinding chamber.

The SAG grindability index test

 · The mill reportedly rotates at 70% of critical velocity (Verret et al., 2011), or 54 rpm (Gonzalez, 2000).There is controversy surrounding the mill rotational speed. The calculation of mill critical velocity (V c) is derived from the balance of gravitational force and the centrifugal force acting on …
