A Hopper Bin In-Boot Agitator is designed to both reduce feed bridging to improve flow and reduce out-of-feed events with no impacts that compromise bin integrity. The Flow-Pro System works by providing gentle agitation inside the bin's plastic boot. It's available for both straight and 30-degree transitions and automatically activates when feed delivery is running. The BridgRid System involves an internal boot-mounted agitating grid that's activated by an external-mounted vibrator. With this system, feed flow is monitored in the auger tube and feed volume in the bin is also monitored.
