For low-dust handling discharge of big bags in closed automatic feeding systems. Big bags are gaining in importance as means of environment-friendly transport and storage in systems with frequent product change.
A fork truck deposits the big bag on a transport pallet in front of the dumping station. There the slings are slipped over the cross bar of the lifting device, the big bag is chain-hoisted, moved to the dumping station, and lowered for docking. 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.
