ABSTRACT:
A method for controlling centrifuges to improve solid-liquid separations, and particularly to achieve desired or optimal solids concentration in the concentrate discharge, is described. The method utilizes mass and solids balances on the centrifuge, together with measured and/or specified values for variables in the balances and for operating conditions of the centrifuge. The system further provides for the measurement of mass or solids concentrations of the concentrate and/or centrate streams as input for a feedback control system which adjusts the shot duration, shot interval or feed rate to modify operation of the centrifuge.
