Abstract

A computer controlled separator device is disclosed. The computer control system monitors the operation of the separator device and makes any adjustments necessary to maintain optimal operation. An operator may input values representing desired operating parameters and/or desired product characteristics of the separator device. Alternatively, these values may be programmed into the computer control system in accordance with optimal product or system standards. The computer control system monitors the operation of the separator device and makes any adjustments necessary to maintain operation in accordance with the selected or programmed values. Specifically, the computer control system may monitor incoming and outgoing product characteristics, i.e. particle weight, particle density, or particle size; and/or operating parameters, i.e. air flow, vibration speed, side tlit, end raise, feed rate, divider knife position and cutout gate position. In response to monitoring signals, operating parameters of the separator device are adjusted.
