ABSTRACT:
There is provided a control apparatus for stopping a large grinding mill driven by two synchronous motors coupled to the mill through respective air clutches. The control includes a clutch actuator control which applies a predetermined amount of pressure of predetermined duration to the clutches sufficient to at least partially close the clutches but insufficient to fully close and lock-up the clutches. The control apparatus further includes an enable control which periodically enables the clutch actuator control to apply the predetermined amount of pressure. The enable control enables the clutch actuator control for a predetermined time duration sufficient to stop motion of the mill and synchronous motors. The present invention provides a system for bringing a mill to a stop relatively quickly without adding significant costs to the mill controls.
