The Fork Truck Loaded or Hoist and Trolley Loaded bulk bag unloaders can be set up as Loss-In-Weight batching systems. These systems can utilize a variety of metering devices such as slide gate valves, flexible screw conveyors, screw or vibratory feeders, rotary valves, etc. and include an integrated scale (load cells mounted within the frame). The operator simply enters a desired batch size and the system will automatically feed that “batch” weight to your downstream process. These batching systems for Super Sack®, big bags, bulk bags, FIBC bags and more, are excellent for individual or multiple ingredient recipe building into blenders or other process equipment.
