T2 Bulk Bag Unloader By Volume

System OVerview

Our T2 bulk bag unloader by volume operates on a volume basis and enables controlled release. The flow from the bulk bag is regulated seamlessly through a built-in Spiroflow conveyor belt system connected to the discharger’s base.

This conveyor type is adept at precisely feeding the contents of bulk bags into a processing container in a manner that is both enclosed and manageable. Tailored to the specific requirements of your application, it can be equipped with a range of options. We offer customized solutions for bulk bag unloading and dispensing, suited to various needs.

Leveraging our expertise in powder handling, we are equipped to suggest the most effective transfer methods for your material. This could include aero mechanical conveyors, a rigid or a flexible screw conveyor, tubular drag conveyor belt systems, or pneumatic conveyor solutions.

Features

HOW IT WORKS & BENEFITS

The T2 universal bulk bag unloader specializes in volume-based unloading. This unloader, constructed entirely from welded materials, features a support dish constructed to fit most bottom-spout bulk bags. The spout of the bag extends through the center of the dish, allowing easy access. A dust-free seal is created by the bulk bag against the support dish. Its robust frame is integrally welded to the dish for added strength.

The Type 2 universal unloader offers a variety of design choices for enhanced flexibility and user convenience. Its discharge chute is tailored specifically to suit the requirements of each application.

The T2 bulk bag unloaders are designed for simplicity and ease of use. Here’s the basic operation process:

Attach the bulk bag to the lifting frame.
Use a forklift to elevate the bag and position it onto the side tensioning frame.
The bag’s weight compresses the springs, positioning the bottom of the bag on the support dish.
The operator gains access to the bag’s bottom spout, with the bag securely supported.
Open the access door, untie the bag’s spout, then close the door.
Activate the spout closure bars pneumatically to start material flow.
As the bag empties, springs in the side frame ensure complete content discharge.
Material falls into the chute, moving via the integrated conveyor to the next process step.
After emptying, retie the bottom spout and remove both the lifting frame and the bag.

The loops of the bag are attached to a bag lifting frame and the liner clamped.

The bag is lifted by forklift on to the robust bulk bag support frame. Spring loaded arms on the support frame gradually raise and tension the bag during discharge. This ensures that the bag is completely emptied and prevents the bag spout or liner from sagging or fouling the take-off conveyor.

Integral chute has an access door for easy bag untying. Patented spout closure bars ensure the bag remains tightly closed until the discharging process starts.

Pneumatically operated massage system, adjustable in position for optimum effectiveness, ensures a consistent flow of difficult products.

An integral conveyor transfers bag contents directly to your process or, in this case, a tanker.
