Bulk Bag Dischargers

Technical Details: T4 Using Single Trip Bags

Single trip bulk bags, are widely used in plant environments for low value or hazardous products which require a dust-free and controllable emptying method.

Our T4 Bulk Bag Discharger (often called a Bulk Bag Unloader) can empty these disposable bags, which have no bottom spout, without waste or spills, even those containing poor flowing products, using various discharge aids and transfer conveyors to suit the application.


  • Static or pneumatic knife
  • Vibratory discharge aid


  • Mobile frame
  • Overhead electric bag hoist
  • Double dust suppression membrane
This single trip bulk bag unloader has a dish with a double membrane to minimize dust during operation.

1. The T4 consists of a robust frame and discharge dish with a knife to pierce the base of the bag. A double membrane with dust extraction facility ensures total containment of dust emitted during bag piercing operation.

Dust is minimized with the design of the T4 Bulk Bag Unloader.

2. The optional double membrane ensures that the bag sits deep within the dish and no dust escapes during discharge.

The knife pierces the bottom of the single trip bag to begin bulk bag unloading process.

3. The bag is ruptured by the knife and product flows from the discharge dish into the integral transfer conveyor.
