A significant amount of settling and packing of granular material had occurred inside bulk bags that had been delivered to the customer’s warehouse. This bulk bag unloader discharges the poorly flowing, granular material directly from the bulk bags into a valve bag filling machine for repacking into 40-50 pound valve bags. A vibrating hopper bin with untie hopper door provides the required agitation to promote material flow at a constant rate. Stairs and a working platform were added because of the tall clearance height under the bulk bag.
The customer loads the bulk bag onto the unloader using a fork lift, but an optional self-contained hoist is available.
