ABSTRACT:
A loss-in-weight gravimetric feeding system is disclosed which includes a prefeeder for receiving and discharging material and at least first and second feeders for receiving material from the prefeeder and discharging the received material to a common collector. The system includes a device for alternately diverting material discharged from the prefeeder to the first and second feeders, circuits for generating a first and second weight signal representative of the weight of material in the first and second feeders respectively, and structure for generating a reference signal representative of a desired mass flow rate of material from a feeder. The system further includes a circuit for alternately comparing the reference signal to the first and second weight signals in synchronism with the diverting device for controlling each of the feeders based on the comparison between the reference signal and the weight signal associated with the feeder.
