Bag-emptying machine – Powder bags and dust extraction

Our fully automatic standard bag-emptying machine empties granulate filled bags of 25Kg. Pallets can manually be fed into the lift at the front or sides. After placing the pallet into the lift, the lift will transport the pallet upwards to a shuttle with integrated grippers. The integrated grippers will grab a layer of 5 bags of the pallet and ride this to the emptying process. Here the shuttle will drive the bags over rotating blades and a unique shaker system. This unique shaker system will ensure that the bags will be emptied for 99.98%. the product will be collected in the product hopper.

Because this machine is divided in several ATEX zones we decided to mount the main control cabinet outside of the high risk ATEX zones.

The capacity of these machines is between 10 and 30 tons per hour. This depends on the configuration of the machine and the product.

Pallet stacker

After emptying the whole pallet, the empty pallet will be transported to the pallet stacker. Here the pallet will be stacked to a maximum of 15 pallets or a desired setpoint. When this maximum or setpoint is reached the stacker will put the pallet stack on the conveyor where it can be picked up with a forklift.


In addition to granulate grains, this machine will also process powder. There is a high explosion risk by processing powder, because of this danger the machine is divided in several ATEX(EX) zones (Zone 20, 21, 22) In all these zones the parts must comply with the ATEX directives of that zone.

Dust cover with connections for extraction

To minimize the cloud of dust we’ve designed two different covers.

A fixed cover that is bolted direct to the bag-emptying machine and a mobile cover. The mobile cover is designed for maintenance, inspection and cleaning purposes when needed this cover can slide open. To ease the inspection work we’ve also designed inspection hatches on the sides of the mobile cover.

In the cover that’s bolted direct to the bag-emptying machine are three openings designed for connecting a dust extraction to the cover. To ease the inspection work we’ve also designed inspection hatches on the sides of the cover.

Maintenance platform with stairs and access door

Because this machine is also processing bags filled with powder preventive cleaning is necessary. The machine is equipped with a platform with easy access to the parts and mobile cover. To gain access a request is made at the desired door. In connection with the ATEX zones, EX certified locks are used.

Belt conveyor

Our machines are often configured with a screw compactor, bag compactor with a rotating roller or bale press.

This client wanted to use their existing container press that’s located outside their building.

To transport the empty bags to this press we have designed a belt conveyor from our bag-emptying machine to the container press.

Every machine configuration is possible

Our machines can be configured or adapted completely according to the wishes or specifications of the customer, please contact us for the possibilities.
