PneuCONVEYOR –  JUMBO BAG UNLOADING STATION

Specifications : 

The pneuCONVEYOR Bulk Bag Unloading System, also known as bulk bag dischargers is specifically designed to provide an easy, clean and economical way to discharge the entire contents of bulk and semi-bulk bags, especially when the material is less than free-flowing. Bulk bags can be placed in the bulk bag unloader by fork lift, hoist or crane from floor level. Standard arrangement includes a bag frame to which the suspension loops of the bag can be attached while the bag is resting on the floor. The bag frame is then raised and positioned so the hooks on the frame engage a counter-balanced suspension frame in the superstructure of the unloader. When lowered, the bottom of the bag rests on a sealing ring in the unloader bed and the tension on the bag loops keeps the bag upright.

Optional : A pneumatically operated actuator petals massage the lower portion of the bag to promote material flow toward the centre of the bag.

The outlet piece of the big bag is fitted over the inlet piece and fixed in place by manually or pneumatically lowering the clamping disc. Then the tie-up string is undone and the big bag slightly lifted by the chain hoist to tension the outlet of the big bag. Safe discharge into the downstream process can start. For flow-resistant bulk material, the big bag supporting table is equipped with an additional vibration device or big bag massager. If desired, the big bag dumping station can be fitted with a low-level detector to enable quick change of the big bag.

Material can discharge by gravity into storage, a process vessel or a conveying system for transfer to another location. Modular construction of the discharge portion underneath the bed facilitates the use of a wide range of devices such as screw feeder, rotary valves, lump breakers, etc. pneuCONVEYOR Bulk Bag Unloaders can be used with Pneumatic Conveying Systems, Flexible Screw Conveyors.

Typical features of Big Bag Discharge Station :

• Convenient big bag lifting from transport pallet into dumping station.
• Reliable dumping of bulk materials into closed production systems.
• For flow-resistant bulk materials, the dumping station will be equipped with vibration support or flexing device.
• Even in applications of with low throughput rates, big bags are expedient as environment-friendly means of transport and storage.
• Suitable also for big bags with insert, optionally available with insert winding device.
