HOW IT WORKS

The T1 Simple Frame Bulk Bag Unloader an economical solution for low volume discharging of free-flowing product.

The bulk bag is lifted into a bag hanging frame by means of a lifting frame. Spring-loaded side support arms, if fitted, keep the bulk bag tensioned during discharge and ensure minimal residue. A receiving hopper with a bag spout spigot, or hygienic liner clamp, is usually supplied beneath the frame. The hopper can be directly connected to a flexible screw (or other types of conveyor) to provide a complete bag unloading and transfer system.

The system will accommodate most types and sizes of bulk bag, provided these are clearly defined.

Bulk Bag Support Frame

A substantial four-legged box section bag support frame incorporates a bag support ring through which the base spout of the bag is located. The unit is manufactured in carbon/mild steel box section finished in two-pack epoxy paint or 304 stainless steel.

Hygienic Bulk Bag Neck Clamp Ring

The manually operated Bag Clamp prevents spillage and dust escaping during discharge. The over-center clamps raise and lower the upper portion which contains seal closing outside the spout. This component is mostly constructed of 304 stainless steel except for the clamps which are cast iron body and plated moving parts.

NOTE: A minimum length of 60cm below the lower tie on the outlet of the bag discharge spout is required when used in conjunction with the Liner Clamp Mechanism to ensure the correct seal on a standard 38cm diameter Clamp Spout (used for bulk bags with outlets greater than 40cm). If the minimum length is less than 60cm or if the outlet diameter is less than 40cm our engineers will need to review the clamp mechanism design.

  • Is discharge of the bag contents required by weight or by volume?
  • Is there provision for restraining and/or removing the inner liner?
  • Is an integral take-off conveyor required?
  • Is there a height restriction?
  • Is there a way to empty small bags in case the bulk bag supply of material is interrupted?
