This continuous loss-in-weight feeder is capable of handling feedrates between 20 and 24,000 lb/h with accuracies of 0.25 to 1.0% on a minute-to-minute basis to two standard deviations. The weigh feeder is controlled by a microprocessor-based system equipped with one million counts of resolution and exclusive disturbance elimination technology. The continuous weighing feeding devices can include pan or tube feeders, screw feeders and belt feeders. The weigh feeder system electronically balances tare weight so the controller senses only the weight of the material in the supply hoppers. — VibraScrew Inc., Totowa, N.J.
