Abstract

A motor-driven drive shaft is coupled to a grinding mill or other unbalanced rotatable member through a clutch arranged to accommodate misalignment, the clutch being so controlled during start-up as to be initially engaged to effect a first limited rotation of the mill in the drive direction, then disengaged to permit the mill to rotate under its own weight through a second rotation in the direction reverse to the drive direction and through a third rotation in the drive direction, and then to be re-engaged during the second rotation of the member in the drive direction. Clutch orbiting is thus reduced if not eliminated.
