T3 Loss-in-weight Bulk Bag Unloader

System OVerview

In the world of industrial powder handling, efficiency, precision, and reliability are crucial. The T3 loss-in-weight bulk bag unloader is a game-changing solution. It is designed to elevate and streamline your bulk material handling processes. Whether you’re dealing with powders, granules, or other dry bulk materials, the T3 unloader can handle it with exceptional precision and efficiency.

Worldwide, industries handle ingredients and dry bulk powders stored in bulk bags. At Spiroflow, we specialize in advanced high-containment systems for unloading and filling these bags. We offer a wide range of standard and customizable equipment solutions, from conveyor belt systems to bulk bag unloaders. Our T3 Loss-in-Weight Bulk Bag Unloader empowers you with precise control over product dispensing from the bag. That control can be adjusted for specific batch quantities or seamlessly integrated into your plant’s processing control for non-stop batch production.

The T3 Loss-in-Weight Bulk Bag Unloader builds upon the proven and tested features of our Universal T2 model by incorporating a bag support dish placed on four load cells. That innovation ensures the utmost accuracy in weighing your product during discharge. Additionally, if needed, the integral transfer flexible screw conveyor can be suspended from the weigh frame, creating a fully self-contained discharge and loss-in-weight dispensing unit. Explore the efficiency and accuracy of our T3 Unloader for your bulk material handling needs.

HOW IT WORKS & BENEFITS

The T3 Loss-in-Weight Bulk Bag Unloader is your solution for precise weight-based unloading. It’s constructed with sturdy welded components, featuring a bag support dish designed to accommodate most bulk bags with bottom-spout. The bag’s spout conveniently passes through the center of the dish for easy access.Our innovative design places the four load cells and summing box in a protected high position on the frame, away from potential harm, water, and dirt. This ensures both safety and durability. Additionally, our bulk bag unloading system offers various control options to suit your needs, and the chute discharge is custom-tailored for your specific application.

Experience the reliability and versatility of the T3 Loss-in-Weight Bulk Bag Unloader for your weight-sensitive unloading requirements.

Operating our T3 bulk bag unloaders is straightforward and user-friendly. Here’s how it works: First, prepare the bulk bag by fitting it with the Bag Lifting Frame. Then, use a forklift to position the loaded bulk bag into place, where it rests on the Side Tensioning Frame with its weight compressing the springs, firmly supported by the Support Dish. You can easily access the bottom spout with the bag securely in place. Open the access door, untie the bag spout, and commence unloading.

As the bulk bag empties, the side frame’s springs maintain constant tension on the bag to ensure complete emptying. The discharged material flows smoothly into the chute. Once the bag is empty, simply re-tie the bottom bag spout, and you’re ready to remove both the bag and the lifting frame. Our T3 bulk bag unloaders simplify material handling, making it a seamless process for your operations.

Using a forklift, the bulk bag is gently placed onto the sturdy bulk bag support frame. On this frame, spring-loaded arms come into play, slowly lifting and maintaining tension on the bag as it discharges its contents. This careful process guarantees thorough emptying of the bag and effectively prevents any sagging or entanglement of the bag spout or liner with the take-off solutions.

The bag loops are securely fastened to a bag lifting frame, and if there's a liner, it's firmly clamped in place for added stability and control.
