From experience in processing plants outside of China, the power rating of the ball mill should be higher than that of the SAG mill . The pebble crusher had an overpowered configuration. The installed power draw of 630 kW (actual power draw of kW) is oversized and therefore had a low operation efficiency.

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powderlike structures. 3.
