Bulk Bag Unloaders

Bulk Bag Unloaders Engineered for Max Dust Containment and Safety While Discharging Super Sacks

Carolina Material Technologies provides 3Sigma's premier Bulk Bag Unloaders that offer Dust-Free Super Sack Emptying with Guaranteed Discharge of virtually any material. Our Super Sack Dischargers are offered in 3 Main Models: Short-Frame Model, Hoist-and-Trolley Model, and the Fork-Truck Loaded Model. There are two main types of agitation for increasing material flow: Massage-It Paddle Agitation (Ultra Heavy-Duty Pipe Agitators that move material into the Critical Flow Path) and Shape-It Vibration System (Shapes the Bulk Bag to the Steep Sloped Platform).

Each model can be custom designed to fit your plant, and with your choice of 3Sigma's Features. The unique Contain-It Access Chamber boasts a large and enclosed bag handling area for the operator the tie and re-tie the bag with ease. The large chamber is engineered to contain any accidental spills or dust that occurs from the emptying process. Custom matched to your downstream equipment: Hopper, feeder, rotary valve, slide gate, screw conveyor, pneumatic conveyor, etc. Inside the chamber, we offer the Close-It™ Bulk Bag Spout Valving System that allows operators to close off and remove half empty bags, or to use as a batch control valve during the bulk bag unloading process. The Clamp-It™ Bulk Bag Spout Clamp provides an air actuated seal that lowers a stainless steel plate once the bag is in place, and secures the bag spout open in order to ensure proper material flow. It features 8” of vertical clearance to manipulate the bag spout, which compares to 2-4” for most competitors. No more knuckle busting! Additional features include: integrated Dust Collection System, Collapse-It™ Bulk Bag Evacuation System, and more.

General Customer Goals

  • Dust Free Bulk Bag Unloading.
  • Unload your densified product reliably with a Bulk Bag unloader.
  • A Bulk Bag Discharger for Total Bulk Bag Discharging
  • Minimal moving parts/ Minimal maintenance.

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.
