ABSTRACT:
The present invention provides a control unit for use with a variable speed system for dispersing, milling or otherwise processing solid particles in liquid. The apparatus used in the system includes a fixed center-drive pulley combination. The control unit automatically resets the pulley combination to a slow start-up position to prevent damage to the system drive train during initiation of a processing operation. In addition, the control unit allows a system operator to precisely and safely adjust the setting of the pulley combination to control the speed of the processing operation. In one arrangement the speed is controlled by manually operated valves that control fluid pressure on opposite sides of a piston that controls the pulley combination. In another arrangement, valves automatically control fluid pressure on the piston to maintain a position in response to a signal from a pressure regulator which is manually or otherwise adjusted to provide a selected speed.
