Better-Weigh Continuous Feeders

The Better-Weigh Continuous Feeders are designed for gravimetric feeding of dry bulk materials where it is necessary to determine actual feed rates on a loss-of-weight basis. Available in seven models with feed rates from 1 to 550 ft3/h, the units provide feeding in either batch or continuous mode, depending upon the arrangement of the feeder’s control electronics. In batch mode, the batch controller is used to control the fast (bulk) and slow (dribble) speeds of the feeder. Accuracies of ±0.5% can be easily achieved in 2-lb or smaller batches, and ±0.25% in 3-lb or larger batches with time spans of 30–90 s. In continuous mode, the feeder's electronic controller is used to constantly monitor loss-of-weight of material per time in order to maintain a continuous loss-of-weight with an accuracy of ±0.25–0.50%. Standard features include a platform or lever balance scale, sealed tactile keyboard, seven-digit numerical keyboard, automatic manual batching, and 2- or 5-ft3 hopper. Sanitary construction is also available.
