Bulk bag dischargers are typically implemented when capacity requirements dictate a change from 50 lb. bulk bags to save labor costs and to minimize dust.  The most crucial aspect in providing you with a successful bulk bag unloader is understanding the bulk bag(s) to be used, your goals and concerns.  Many suppliers overlook the actual bulk bag and dive into offering you their standard bulk bag unloader – the “one size fits all” mentality.  Bulk Bag items of concern include: Dimensions; Lined or Unlined; Loose Liner, Tabbed Liner or Glued Liner Flat Bottom or Cone Bottom; Single Trip or Multi-Trip; Bulk Bag Outlet Spout Dimensions; Bulk Bag coatings, etc.
