Carolina Material Technologies provides 3Sigma's premier Bulk Bag Unloaders that offer Dust-Free Super Sack Dispensing with Guaranteed Discharge of virtually any material. Our Super Sack Unloaders 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 super sack unloader model can be custom designed to fit your plant, and with your choice of 3Sigma's Features.
Super Sack Unloaders and Bulk Bag Dischargers Advantages
Bulk Bag Discharger System
The unique Contain-It™ Access Chamber boasts a large and enclosed bulk bag handling area for the operator to tie and re-tie the bag with ease. The large bulk bag chamber is engineered to contain any accidental spills or dust that occurs from the super sack dispensing 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™ Super Sack Valve 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.

Super Sack Unloader General Information

Bulk bag unloaders (also called bulk bag dispensers or super sack unloaders) typically consist of a steel frame that supports the unloading of material from a FIBC super sack into the industrial process. However, not all bulk bag unloaders are created equal. We provide 3Sigma Bulk Bag Unloading Systems that make handling of super sacks practical and efficient by providing an easy and safe method to lift, support and discharge material. 3Sigma Bulk Bag Unloaders were specially engineered for dust-containment and ease-of-access for the operator. At CMT, we integrate design and integrate our super sack unloaders with other process handling equipment in order to provide controlled, regulated discharge with a variety of feed devices and weight control options.
General Customer Goals
Dust-Free Bulk Bag Unloading.
Discharge difficult/densified Products
A Bulk Bag Discharger for Total Bulk Bag Discharging
Minimal moving parts/ Minimal maintenance.

Super Sack Unloaders are typically implemented when capacity requirements dictate a change from 50 lb. bags to FIBC bulk bags, in order to save on material and labor costs. Understanding the properties of your material in the FIBC bags and setting your goals is a critical component to desigining your system.  Many suppliers overlook the actual bulk bag and dive into offering you their standard bulk bag unloader – the “one size fits all” mentality.  However, the properties of the Bulk Bag can impact the unloading process. Some 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.
