Mill load sharing – Maintains equal torques on dual pinion mills throughout the whole speed range. Controlled rollback – Prevents backlash and reduces downtime. Mill power ride through – Keeps the mill operating even under voltage dips. Over-duty cycle – Avoids unexpected downtime if the mill gets overloaded.

design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
