Abstract
A method is provided to automatically control an infeed gate of a centrifuge to regulate the rate of incoming charge and thereby maintain a desired building rate for a charge wall being formed along inner sidewalls of a rotating centrifugal basket by measuring the charge wall thickness which forms, determining a fill rate at which the charge material enters the basket, and comparing the determined rate to a desired fill rate. Closure of the infeed gate is also controlled to gradually approach a minimum flow rate. A method is also provided for sensing an unstabilizing wobble of the centrifugal basket and closing the infeed gate in response. The automatic control of the opening and closing of the gate not only improves the capacity of the centrifuge, but also allows for remote operation.
