Big-Bag discharge

big-bag-discharge

Big-Bag discharging systems are specifically designed for discharging a large variety of products from different types of Big Bags. They eliminate dust emissions, product loss or product contamination. This modular range encompasses the discharge of single or Multi-trip bags, with or without plastic liner. Also a number of unique options are available for the safe and hygienic discharge of food ingredients, pharmaceutical products and toxic materials


Modular concept
The TBMA range is based on a simple but very flexible modular concept, whereby the basic models can be extended with several options to obtain a complete solution for discharging Big-Bags. TBMA has a wide range of expertise in the application of this type of equipment with proven reliability in practice. This is essential for a correct assessment of the right type of system for your particular situation.
The modular set-up makes it possible to customise every system taking into account all customer specifications regarding; type of product, type of bag, environmental aspects, system capacity and budget.

Many options and execution possibilities:
In order to fully accommodate our customer requirements the basic discharge hopper can be combined with a number of options and executions.

  • Customised top- and bottom frame
  • Multi-functional rigging frame suitable for both hoist and fork lift truck
  • Three-edged cutting knife for single trip Big-Bags
  • Dust-free discharge by means of rubber dust membrane
  • Vibration motor for efficient discharge of product
  • Liner tensioning and clamping mechanism for lined Big-Bags
  • Containment enclosure for handling toxic or hazardous products
  • Sanitary execution
Dust-free solution with liner clamping mechanism.
The specially designed liner clamping mechanism enables a dust-free seal of the liner before product flow is allowed into the down stream system. It realises a completely clean and dust-free discharge eliminating product loss or product contamination. Operation can be executed in either a manual or pneumatic version.
Liner clamping mechanism

Optimal handling of loose inner liners
The rigging frame incorporates a unique liner tensioning and retraction system.
This system secures the loose inner liner to the rigging frame and is automatically tensioned during discharge. It avoids product entrapment and enables a complete, dust-free discharge. After the discharge cycle is complete, the inner liner is
retracted by the system and rolled up to a small and compact bundle.
Afterwards it can be removed from the easily accessible retraction frame.
