Bulk Bag Unloader System to unload additives for mixing and blending

Bulk Bag Unloader System

Bulk Bag Unloader System

A bulk bag unloader system, containing three unloader stations, is used to precisely unload additives into a mixing and blending system. Each unloader station contains an over head rail with a powered hoist and trolley to lift the transport frame and bulk bag into the unloader station.

Under the bulk bag is an untie hopper and delumper to remove any lumps before entering the vibratory feeder.  The vibratory feeder meters the powdered material into a pneumatic conveyor. The pneumatic conveyor transports the material to a weight hopper above a blender.

Each bulk bag unloader station is on load cells with a PLC / weigh controller. This is used to control the flow rate of the material into the pneumatic conveyor. Controls include an auto manual selector switch to allow for manual operation of the components. Each station contains a free standing dust collector to collect dust from the unloader station.  All three unloader stations report to a central plant PLC system. All parts are made of 304 stainless steel.
