The five bulk bag unloaders and five volumetric screw feeders accurately feed material to a centrally located portable hopper.

An operator uses a forklift to lift the bag-lifting frame and empty bag from the unloader.

The scale’s microprocessor controller (center, silver box), which is programmed with various batch formulas and target weights, controls the portable-hopper loading operation.

"Better-Weigh®" Continuous Weigh Feeders Deliver Highly Accurate Gravimetric Feeding In Batch Or Continuous Applications
Metalfab, Inc., a leading manufacturer of integrated dry solids processing systems and equipment, has announced availability of their "Better-Weigh®" Continuous Feeders 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), "Better-Weigh®" Feeders are designed to 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 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 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.
