Figure 3 shows a ball mill with a dual pinion drive 2x 6500 kW with low speed induction motors (LSIM). The dual pinion drives demand tight tolerances in the torque between the two motors [2] to dynamically equalize the load on both pinions so that, in the long run, their duration is secured and the system availability guaranteed.

The clutch's primary role on the dual-pinion, direct-drive geared mill is to provide smooth starts during mill startup. When the mill is running, the clutch also serves as a torque "circuit breaker," reducing costly repairs and downtime by protecting the pinions and ring gear from potential damage caused by large pieces of grinding material.
