Bulk Bag Dischargers

For this reason, the Model T9 has bag massagers at the corners of the bag as well as the base.
A patented pneumatic bag tensioner and an inner liner clamp prevents the possibility of creases being formed during unloading which can trap residual material.
Height adjustment for bags of different sizes is provided as well as a lifting frame locator for the correct alignment of the discharger with the vessel or other piece of equipment into which the material is being unloaded. This feature enhances containment of the product.
Special design features permit Cleaning in Place (CIP).

 number of products handled in bulk bags are of a fine, powdery and invasive nature and total containment during unloading is necessary to prevent contamination of the local atmosphere and health and safety hazards. The problem is exacerbated where the product is volatile, toxic or presents an explosion risk. Spiroflow has developed the T9 bulk bag discharger for use where total dust containment is essential.

A sealing device inflates inside the bottom spout of the bag and seals it during the emptying process to eliminate the risk of dust emission.
It also operates in conjunction with an automatic spout stretching device to promote a smooth and cylindrical path for flow of material directly into a process vessel or integral conveyor.
This patented feature is of special value where products with poor flowing characteristics are being handled.
It is important to ensure total discharge of product from the bag when invasive powder is being unloaded in order to prevent the escape of material when the emptied bag is removed.
