Centrifugal separator control

摘要

A method and mechanism for controlling the operation of a centrifugal separator having a relatively rotating drum and screw conveyor whereby the speed of each is measured and the torque for driving the screw is measured and the speed differential control is in a predetermined functional relationship to the torque and at a particular maximum and minimum value of torque, the speed differential being changed independently of torque and when a predetermined change in torque is obtained, the predetermined functional relationship between the torque and speed differential being changed to a different characteristic step-wise with the characteristic or relationship being shifted step-wise.
