Better-Weigh continuous feeders are used 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 cu ft/hr (larger sizes available), these feeders are designed to provide feeding in either batch or continuous mode depending upon the arrangement of their 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 less batches, and + 0.25% with 3-lb or greater batches with time spans of 30 to 90 seconds. In continuous mode, the 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% to 0.50%. Standard features include a platform or lever balance scale, sealed tactile keyboard, 7-digit numerical keyboard, automatic manual batching, and 2- or 5-cu-ft hopper. Sanitary construction is also available.
