The quick and efficient solution for bulk bag discharge and dust control
Hapman bulk bag unloaders (or bulk bag dischargers) are engineered to safely and effectively unload large bags, commonly known as Flexible Intermediate Bulk Containers (FIBC). The structural framework is designed for your specific application.
Each bulk bag unloader is equipped with the features you need to maximize your bag handling process – from a cantilevered I-beam to an electric hoist and trolley for loading and unloading of bulk bags without the use of a forklift. Other bulk bag unloader designs include frames for forklift loading, and low-profile units for use in low ceiling areas where lack of overhead room would impede the full extension of the forklift. Also available are bulk bag unloader half-frames that can be used with existing hoist and monorail systems, a loss-in-weight option for uninterrupted feeding directly from bulk bags in batching operations, and other engineered designs for specialized requirements.

BULK BAG CONDITIONING
Integrated hydraulic conditioners for the Bulk Bag Unloader allow for effective processing and improved material flow of bulk bags or FIBCs. The hydraulic conditioners are engineered for the break-up of very hard agglomerations. The system uses engineered steel compression plates designed to push on the bag at staged intervals, breaking up hard agglomerations. Bag conditioners can be incorporated into a Bulk Bag Unloader or designed as a separate stand-alone unit.

Pneumatic agitator paddles can be used in conjunction with hydraulic bag conditioners or as a stand-alone option. Also integral to the Bulk Bag Unloader, the pneumatic agitator paddles massage the bag while the material is discharging. The massaging action reduces bridging and provides a continuous and positive material flow.

Low-Profile Bulk Bag Unloader
Our patent-pending low-profile unit allows a forklift to be fully extended, even in low ceiling areas. Our patent-pending slide rail design serves as a guide for the forklift driver for placement of the top section.
Custom Equipment
Like all Hapman equipment, our bulk bag unloader systems can be designed to meet your specific needs by our experienced and knowledgeable application experts. A common reason for a custom unit is low ceiling height; click here for more details on our patent-pending, low-profile unit.
Our Bulk Bag Unloader is often used in conjunction with other material handling equipment. Here are just a few examples of how our bulk bag discharge equipment has helped facilities in all material handling applications maximize their bulk purchases by optimizing how the bags are unloaded.
Dry Granulated Material – This customer had a challenging material handling issue. The product they purchased in bulk bags was of various size granules. Their process could only handle smaller-sized particles. To effectively handle the bulk bags and optimize larger-quantity material purchases, we helped this customer by designing a complete unloading and pre-processing system. This picture shows the bulk bag unloader with a hoist and trolley assembly, iris valve at the bag discharge with the spout untie box and hopper. Our Vacuum Conveyor lifts the material into a screener, which separates the larger particles out of the process and delivers the small particles directly to the assembly line.
Fine Powder – In this application, our customer used a hoist and trolley-style unloader to empty the large bags of protein powder. The discharge valve is a pinch valve, which allows the operator to close prior to the release of material, thus preventing a large instantaneous load on the system. This unit includes an untie box and a hopper. Our Helix® Flexible Screw Conveyor is mounted off of the hopper, elevating the powder into the mixer.
