Bulk Bag Systems for Unloading and Discharging
Heavy-duty bulk bag unloaders that will unload and discharge any and all material from bags. If it can be unloaded from a bulk bag, jumbo sack, FIBC, or Super Sack® – we can do it!
The economic and ergonomic advantages of bulk bags in handling bulk material is creating a steady conversion from many alternative packages (small bags, gaylord boxes, rigid IBC’s, etc.). Our Bulk Bag Unloaders provide a safe, dust-free, and convenient way to unload and discharge bulk bags. These are available in several models to accommodate the specific needs of your big bag discharging application. From something as simple as an unloading bag hopper to fully integrated frames with all components required to deliver a complete bulk bag unloading system.
Our bulk bag unloader incorporates the “live bottom” technique with an isolated hopper and a 1500 pound force industrial gyrator. If we test your material in our lab, we will guarantee complete discharging of material from your Super Sack® or bulk bag. See this article for more information on this technique vs. Paddle Agitation unloaders – read more. FormPak bulk bag unloaders are available with any type of take away conveyor, feeder, valve, as well as optional features like access doors, downspouts, iris valves, and downstream process equipment to condition and control your product. We can even set up your bulk bag unloader as a LIW (Loss-In-Weight) or GIW (Gain-In-Weight) batching system.
Bulk Bag Frames Types
Fork Truck Unloader
The fork truck style bulk bag unloader is our most popular and is a very cost competitive, fully integrated system. It represents the best all around, competitively priced, industrial duty bulk bag unloader on the market. With features like easy bag height adjustment, offset receiver arms for straight in fork truck loading, and heavy structural frame, the FL unit is your best solution for complete bulk bag discharge.
Hoist and Trolley Bag Unloader
The hoist and trolley big bag unloader allows staging of Super Sack®, big bags, bulk bags, FIBC bags with a forklift or pallet jack (where access by forklift isn’t available). An integral I- beam with a pendant controlled hoist and trolley, provides quick and reliable loading of the bags with one operator.
Half Frame Bulk Bag Unloader
We also offer half frame bulk bag unloading units for applications where existing hoists are available, or simply wish to support the big bag with a fork lift. Another bulk bag discharging option is our Retro-fit Bulk Bag Unloader Kit that allows you to utilize an existing frame but add the proven effectiveness in unloading Super Sack® of non-free flowing materials via the gyrating hopper.
All but our Half Frame bulk bag unloaders can be made to have Loss-In-Weight batching capabilities. This is done by adding load cells (scale) to the the bulk bag unloader frame, and supporting a screw, screw conveyor, flexible screw conveyor, valve, or other feeding or metering device. The load cells are connected to a scale controller that allows for automatic batching via bulk and dribble feeding. BagFlo 500-LIW
- Send us your Super Sack® of material for a free unloader test.
- We offer free testing and evaluation of bulk bags in our unloaders.
- When we successfully test your material in our lab, we will guarantee the performance of our equipment for that material.
- All you have to do is send us a full and empty Super Sack® to our lab in St. Louis (freight costs to and from our lab are the responsibility of the customer).
- You are encouraged to witness these tests, but we can provide video and photographs as well as a written report of results if your time does not permit
