Big Bag Emptying stations

Our big bag emptying stations are generally designed for big bags with a capacity up to 2 tons.
Different alternatives and options are available to meet customer’s requirements.

In case of a big bag emptying station for bad flowing products, we can provide a vibrating frame as well as a massaging system with pneumatically operated cylinders to enhance the discharge (or a combination of both systems in the worst case).

The design of this station will allways depend of the characteristics of the product which has to be discharged.


The big bag emptying station is provided with a lifting frame, adjustable in height, with automatic big bag tension device which allows a completely emptying of the bag. How it works: by loosing weight during emptying, the big bag will be tensioned automatically by a telescoping spring system.
 
Optionally, we offer the possibility to shut even partially filled big bags.

The handling of the big bags generally occurs by means of a forklift or a crane runway. This crane runway might be integrated in our station too, to drive the bags in the emptying station.
 
The big bag emptying station may be installed at a fix place or alternatively be provided as mobile station.

In case of big bags with inner liner, we also offer optionally big bag cruciform with device for automatic coiling of the inner liner.

Generally, our big bag emptying station is combined with

a further conveying or dosing of the product:

- in case of good flowing products, we will provide a reception hopper under the station, which is designed to connect a spiral conveyor (by means of a clamp ring), which  will convey the discharged product with the required throughput to the application site.

Alternatively, a suction pipe can be mounted as part of a pneumatic conveying system.

-in case of poor flowing products, a hopper with a combined discharge and metering system can be connected under the big bag emptying station. This hopper can even be designed additionally as a tip sack hopper.
