T2 Bulk Bag Unloader By Volume
Overview
Our Universal T2 Bulk Bag Unloader provides controllable discharge by volume. Flow from the bulk bag is easily controlled by an integral Spiroflow conveyor coupled directly to the base of the discharger.
This type of conveyor can be used to accurately meter bulk bag contents to a process vessel in an enclosed and controlled manner. Based on your application needs it can be fitted with a variety of options and custom bulk bag unloading and discharging or dispensing designs are always available.
Given our powder handling expertise, we can recommend the best transfer method for your product, whether it is by aero mechanical, flexible or rigid screw, tubular drag or pneumatic conveyor.

HOW IT WORKS & BENEFITS
The T2 Universal Bulk Bag Unloader is used for unloading by volume.
This bulk bag unloader is of all welded construction with a bag support dish that will accommodate most types of bottom-spout bulk bag. The bag spout passes through the middle of the dish where it can be accessed. The bulk bag provides the seal against the support dish for a dust free seal. The heavy-duty frame is welded directly to the support dish.
The Type 2 Universal Unloader can incorporate a number of design options in order to provide maximum versatility & ease of use. The discharge of the chute is custom made to fit the application.
How It Works
Our T2 bulk bag unloaders are simple and easy to operate. The basic sequence of operation is as follows:
- A bulk bag of product is fitted with the bag lifting frame.
- The operator lifts the bulk bag into place with a forklift.
- The lifting frame sits on the side tensioning frame.
- The weight of the bag compresses the springs & the bottom of the bulk bag rests on the support dish.
- With the weight of the bag safely supported, the operator can now freely access the bottom spout of the bag.
- The operator opens the access door, unties the bag spout & then closes the access door.
- The operator pneumatically opens the spout closure bars & material flow begins. As the bag empties, the springs in the side frame will keep a constant tension on the bag ensuring complete emptying of its contents.
- Material falls into the chute & the integral conveyor moves material to the next step in your process.
- When empty the operator reties the bottom bag spout & removes the bag & lifting frame.
Features
- Full dust control
- Designed to discharge poor flowing materials
- Suitable for all bulk bag types and sizes up to 6.5 ft (2m) high and 2 tons (2,000kg) in weight
- Bag tensioner ensures total emptying of bag contents – no waste or spills
- Automatic transfer of contents via integral take-off conveyor
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.
SPECIAL APPLICATIONS
Although we have an extensive line of bulk bag unloaders we often design custom equipment for our customers. Here are a few of our more unusual designs:
This custom bulk bag unloader has a horizontal screw conveyer that can move material to one of two outlets. This unit also has an integral dust collector, hopper vibration and bottom bag massage.
This custom bulk bag unloader is fitted with a custom designed pneumatically operated lids.
MODELS & SPECIFICATIONS
The T2 bulk bag unloader is one of the several bulk bag unloader and discharger designs we offer. Features of our various models are typically mixed and matched to accommodate specific application needs. And, of course, we regularly build custom designs. Here is a list of our basic models. Your Spiroflow Sales Engineer will evaluate your needs and recommend the best configuration to do the job.
