Big bag discharging station

for a high flexibility

Big bag discharging station – modular structure for every demand

various models for an efficient discharge of bulk materials

The big bag discharging stations by OAS allow an efficient handling of bulk materials and guarantee smooth discharging processes. The modular structure of the units conforms to the diverse tasks of the bulk material industry and to your individual requirements. The discharging stations can be combined with sack chutes, fibre dosing devices, and site silos as well as many other components to become custom fit bulk material stations. From discharging, to dosing, to the conveying into the downstream process – OAS covers the entire field of materials handling and assists you with the conception of plant construction.

Big bag discharging station: functions and components

The frameworks of the stations fulfil various functions. Chain blocks and portable top frames serve an economic change of the big bags. Adjustable top frames allow discharging of big bags of different volumes. Fast and complete emptying of the trading units is ensured by the automatic tightening of the big bags by means of a spring system in the top frame or by means of an automatic height adjustment of the chain block. Supports are designed as crush protection to provide for safe handling of the big bags.

Frame function at a glance:

  • changing of big bags using a chain block or portable top frame
  • adjustable size of top frame
  • automatic tightening of the big bags by means of a spring system or a chain block
  • support as crush protection

Moreover, the big bag discharging stations can be further adjusted to the corresponding demand. Thus, special connecting systems provide for low-dust connection of the big bags, pneumatic discharge devices provide for loosening and aeration of the bulk material so as to support the flow of material. When emptying disposable big bags, pyramid knives or cross knives open the fabric to allow the material inside to rapidly flow into the further process. Buffer containers controlled by request messages can be used to cover the big bag changing time without resulting in bottlenecks regarding the material supply.

Special functions at a glance:

  • low-dust connection
  • pneumatic discharge devices
  • cross knives for discharge big bags
  • buffer containers controlled by request messages

The plant engineering by OAS copes even with very particular ambient requirements. Thus, we implement stations completely fitted in a housing as well as projects where the construction height is limited. Even substances subject to ATEX can be stored and conveyed without problems. We have the proper solution to your individual problem definition!

The process in view

Storage and removal of material is one thing – further transportation and dosing into the downstream production process is just as important. We offer holistic solutions, e.g. featuring

  • auger fillers or
  • pneumatic conveying equipment (also for abrasive substances), such as suction conveyors, dense-phase conveyors, or plug conveyors.
