Plant-Wide Weigh Batching System

Automated plant-wide weigh batching system simultaneously weighs up to seven major ingredients received in bulk bags and unlimited minor ingredients received in 50-pound sacks, pails or boxes, and conveys weighed batches to a downstream blender that feeds a bulk bag filler and a paper sack filling machine. System components include five loss-of-weight Bulk-Out™ bulk bag dischargers with large surge hoppers and rotary airlock valves; two loss-of-weight Bulk-Out bulk bag dischargers with small surge hoppers and flexible screw conveyors; two loss-of-weight bag dump stations with flexible screw conveyors; a check-weighing hopper; a Twin Centerpost™ bulk bag filler; a Pneumati-con® dilute-phase pneumatic system including blower, filter receiver and conveying lines; and a programmable controls package. Each of the large surge hoppers accommodates the entire contents of a bulk bag containing a major ingredient, affording operators sufficient time to load full bags into the frame as material is removed at high rates through a common pneumatic line terminating at the filter receiver.
