Will ground maze run out of a fibreglass bin ? Or will it bridge?

I’d say bridge. It’s like flour from previous experience

If using it quick should be OK just.
I had some, was a pain. And loads got stuck

Better in a steel bin. At least then you can rubber hammer the side of the cone. Make sure it doesn’t go in when it’s fresh ground and warm. It will cool and stiffen.
fertilizer company I deal with have an electric motor with a bolt in a pulley. It’s out of balance and vibrated like crazy. It’s bolted to the bottom cone supports and keeps it flowing pretty good.
