Model 821 Bulk Bag Unloader

Normally furnished as an integral component of a dry solids handling system
provided by Acrison, product discharging from the Model 821 Bulk Bag Unloader
flows directly into auxiliary equipment mounted beneath.

For example, operation of the bulk bag unloader may be
controlled by probes located in the supply hopper of an
Acrison volumetric feeder, or in the collection hopper of a
mechanical or pneumatic conveying system for transportation
of the material elsewhere. In other applications, operation of
the unloader is initiated at the same time a valve is opened,
typically to supply product to refill an Acrison ‘Weight-Loss’
Weigh Feeder, which operation ceases when refill has been
satisfied and the valve closes.
