Metalfab’s Better-Weigh continuous feeders work in gravimetric feeding applications 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 cu. ft. per hr. (larger sizes available), 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 achieved in 2-lb. (or less) batches, and +/-0.25% with 3-lb. or greater batches with time spans of 30 to 90 seconds. In continuous mode, the feeder’s electronic controller constantly monitors loss of weight of material per time to maintain a continuous loss of weight with an accuracy of +/-0.25% to 0.50%.
