With regard to individual operating site, we recommend different systems. Basically, there is a difference between sack filling and weighing machines and big bag loading stations.

The sack filling and weighing machine is used for slump of small casks between 25 and 50 kg. Material is filled into open bags, which are closed by sewing machine. Optionally those semi-automatic systems also provide a conveyor road for removing completed bags. Finally, the bags are stored as single pack or stockpiled on pallets before vending.

In many places customers require to pack free-floating goods in big bags.
For this reason, we designed so-called big bag scales. Apart from simple constructions, which have to be handled 80 % manually, we also provide complex systems realising fully automatic processes.

Using BITZER Big-Bag loading station effects an automatic dosing and legal for trade weighing of big bags.

The big bags are attached to pneumatic handle brackets. For quick and efficient operation the brackets in the back move towards the operator.
By using accurate dosing electronics, loading processes are automatically optimised. This automatic system enables the filling and weighing of approx. 30 up to 35 big bags per hour.

Regarding the material, the big bag station can be designed with or without rapping gear. Due to the modular construction the customer is able to choose freely the level of automation, e.g. automatic stockpiling on pallets, automatic handing-over into further working steps etc.
