Griffin - Weigh Batcher Filter Vents
Batcher Filter Vents are used to filter and release the displaced air caused by product filling the weigh hopper. The filtered product is then returned to the weigh hopper by gravity through the action of the shaking bags. Both Natural Vented and Blower Assisted models are available.
Automatic Overfill Control System
The Griffin Overfill Control System, consisting of a closing valve, limit switch and control panel, completely automates silo filling and venting while preventing overfill and resulting damage. It is designed to operate on any pneumatic silo filling system with any number of fill pipes. If the high bin signal is clear when the trucker connects his hose to the fill pipe, the butterfly valve will open and the silo will accept material. When the high bin indicator is activated, an alarm will sound telling the trucker to stop his unloading operation. In 90 seconds the butterfly valve will close, sealing off the fill pipe and making it impossible for the trucker to continue pumping in material. The bags in the dust collection system will then automatically shake.
