Automatic big bag emptying

Automated and dust-free emptying of big bags

Material handling for hazardous products or bulk goods is increasingly being handled using big bags. For this reason, we have developed the automatic emptying system for big bags. With maximum emptying performance and semi-autonomous handling of big bags, this system is an absolute novelty on the market.

The process is automated: The big bag is hooked in at the pick-up point by the operating personnel, then fed fully automatically to the emptying position via a positioning system, then cut open by a circular knife and emptied. Thanks to the use of the circular blade, even bulk materials that form strong bridges or are agglomerated can be discharged from the big bag safely.

Fully automatic system for emptying

Hazardous bulk materials

Your employees do not have to expose themselves to any danger.

High emptying capacity

Emptying of up to 25 big bags per hour possible.

Efficient handling

Automated big bag handling guarantees high system availability.

Ready for Industry 4.0

Intelligent networking of machines and processes.

Automatic big bag emptying station


Dust-free emptying of big bags with shredded Li-ion batteries for conveying to a downstream process with as little operator intervention as possible.

The solution

  • A semi-automatic big bag discharger system was used for this project
  • The rotating circular blade automatically cuts open big bags with and without discharge spouts
  • The product is fed to the downstream process via a screw discharge base and a discharge screw
  • The traverse automatically places the emptied big bag in the big bag compactor (BSV)
  • Operator intervention is only necessary when hanging the big bag in the automatic traverse and when changing the BSV big bag

Big bags should be emptied automatically.

The solution

  • The operator manually hooks the big bag loops onto a lifting beam.
  • The big bag is automatically lifted to the emptying position and emptied by itself.
  • The completely emptied big bag is automatically unhooked from the lifting beam and pressed in a big bag compactor to save space.
