Big bag unloading machine with glove box BBU

bulkpowdergranules

Overview
The big bag emptying station (BBU) is used to empty powder or bulk material from a big bag (bulk bag) and convey it directly to downstream equipment in combination with vacuum conveying systems. Typical uses include transfer into silos and gravimetric dosing into reactors or mixers.

Key description
The BBU accepts standard bulk bags/FIBCs, big bags, jumbo bags, super sacks or tonne bags. It is optimized for low-dust operation with vacuum conveyors and can handle most materials. Poor-flowing products are assisted by massaging paddles and product-loosening devices. Clumpy materials and agglomerates can be reduced by an optional lump breaker to enable reliable pipeline conveying. For higher containment, the BBU can be equipped with a glovebox: docking/undocking is performed through gloves and negative pressure prevents air and dust escape. An optional emptying flap and support table allow emptying of small sacks and containers.

Features and options

• Suitable for big bags (bulk bags/FIBC) up to 1,400 kg
• Low-dust, low-contamination handling in conjunction with vacuum conveyors
• Integrated filtration and dust recovery system for bag changes
• Loading options: forklift pickup or integrated crane/hoist
• Massaging paddles and product-loosening devices (optional)
• Optional lump breaker for crushing clumps and agglomerates
• Glovebox option for high containment (prevents air/dust escape)
• Combined systems available (e.g., with bag rip-and-tip stations)
• Modular construction enabling customized configurations
• Optional emptying flap and support table for small sacks and bins

Applications
Controlled emptying and transfer of powders and granulates into vacuum conveying systems for further processing or storage (silos, mixers, reactors). Suitable for food, chemical, pharmaceutical and other industries requiring low-dust handling.
