Hoppers, ProBox Stands, Bulk Bag Unloaders with Scale Supports

Surge hoppers, ProBox stands, and bulk bag unloaders engineered to feed and support gross or net weigh bagging scales.
Bagging scale support structures provide storage and controlled product flow above a gross or net weigh bagging scale while supporting the weight of the product, scale, and feeding equipment. Configurations include surge hoppers, ProBox-style discharge stands, and bulk bag unloaders.
Each system is custom engineered for the application. Standard construction includes 3/16-inch hopper walls and heavy-duty tube steel framework with a 2-part epoxy finish. Mild steel, 304 stainless steel, and 316 stainless steel construction are available, along with multiple storage capacities and options such as operator access mezzanines, hopper lids, and level sensors.

Bulk Bag Unloaders for Bagging Scales
Bulk bag unloaders discharge material from bulk bags, big bags, or Super Sacks® into a surge hopper feeding a gross weigh or net weigh bagging scale. A removable lifting cage supports the bulk bag from all four corners, while an access door allows the operator to untie the discharge spout and use an iris valve to control product flow. A gyrator can be cycled as needed to promote material flow and help fully empty the bag.
- Removable bulk bag lifting cage with four-corner support and fork tube guides
- Heavy-duty cradle assembly with 6-inch tube steel framework
- Operator access platform with ladder
- 37 cubic foot surge hopper with bulk bag support flange and hopper lid
- Stainless steel construction available with continuous internal welds ground smooth and a food-grade #8 bead blast finish
- Extended-frame configurations available for mounting an open mouth bagging machine below the unloader
For a complete repackaging system, the bulk bag unloader can feed an open mouth bagging machine mounted below on a portable, adjustable stand. An iris valve regulates product flow into the bagging scale, while a pneumatic bag clamp and two-position flow gate provide controlled, accurate filling.
One system configuration can fill open mouth paper bags with granular or powder products such as zeolite and guar gum at approximately 4-6 bags per minute. A bag shaker helps empty each bulk bag, while filled bags travel by conveyor through a pedestal-mounted sewing head before being stacked on a self-raising/lowering pallet loading station.
