Gravimetric Screw Feeders

Metalfab “Better Weigh®” Continuous Weigh Feeders

For highly accurate, gravimetric feeding of dry bulk materials in batch or continuous operation

“Better-Weigh®” Batch/Continuous 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 ±0.5%.
