Discharge Product from Bulk Bags into Batching Mixing System

This is a bulk bag unloader that discharges product from a bulk bag into a batching/mixing system. The bulk bag unloader is loaded by a fork lift placing a bulk bag in the frame of the BBU. Product is drawn out of the bulk bag via an enclosed vibrating feeder to meter product into a paddle mixer for blending with other dry ingredients. The feeder is controlled by a loss in weight system comprised of load cells and controller to dispense a specific weight per batch.

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.
