Smooth Operators

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.
