2018-3-4 · Therefore the SAG mill speed could not be controlled using the microphone based signal and instead was manually controlled/set by the control room operator. Thus operation/speed of the mill could and would change significantly based on a particular operator running the mill and their overall level of mill operation experience and skill.

The SAG mill (Morgardshammer, 8.0 m x 3.95 m, 3.8 MW, fixed speed) uses 125 mm diameter balls as grinding media at an average 10% to 12% charge volume. Water is added to the mill to keep a charge density of 60% to 85%. The SAG mill discharge screen size is 8 mm. The -8 mm stream is diverted to a cluster of cyclones.

2014-10-1 · ball mill. This is evidenced by the lower gradient of the size distribution (in log-log space) and the smaller exponent in the power function, hence larger fractal dimension (Turcotte, 1986). This effect is similar to a SAG mill (although to a lesser extent) and results in the P80 being an ineffective measure of the degree of size reduction.
