Defining Your Bulk Bag Unloading Requirements

Before starting to specify the bulk bag unloader or bulk bag discharger type, options and customizations, first consider the material, process needs and bag requirements. Some of the most important questions to ask to ensure you end up with a safe and reliable bulk bag discharging solution include:

  • Will the bulk bag unloader need to accept varying bag sizes?
  • Will the bulk bag unloader handle poor flowing products?
  • Is there a forklift available or is an integral hoist needed?
  • Does the bulk bag unloader provide a controlled flow when the spout is opened?
  • Does the bulk bag unloader have a bag tensioning device to ensure all product is discharged?
  • Is discharge of the bag contents required by weight or by volume?
  • Is there provision for restraining and/or removing the inner liner?
  • Is an integral take-off conveyor required?
  • Is there a height or space restriction?
  • Is there a way to empty small bags in case the bulk bag supply of material is interrupted?
  • Does your plant require a hygienic bulk bag unloader or USDA/FDA approved equipment?
  • What dust control features are incorporated into the bulk bag unloader?
    • When untying the bag spout
    • While the product is being discharged
    • When the inner liner is being removed
    • When the bag is removed and folded for disposal
  • Is the product or environment hazardous?
  • Is static grounding and monitoring required?
  • Is the environment covered by NEC regulations?
