Bulk bag weigh batch system with pneumatic, flexible conveyors

New automated bulk bag weigh batching system feeds ingredients to a central weigh hopper at mezzanine level using four flexible screw conveyors, and transports pre-weighed batches to a downstream blender using a pneumatic conveying system. Bulk bag dischargers feature a cantilevered I-beam with electric hoist and trolley to raise and position bags without a forklift. Units are equipped with bag activators that raise and lower opposite bottom edges of the bag at timed intervals, loosening compact materials and promoting material flow into the discharge spout.
