some bits of thoughts that just came to me.
The wheel is mounted on an arm, with a planter wheel bearing, there dirt cheap and made to run in dirt all day long.
the blade looking part that is welded to the drive head is a scraper that sticks down the side of the drive tube an keeps the sand from sticking and building up. Petrobond/Oilbonded sand needs pressure to be conditioned correctly.
The drive head is made from a hunk of 4 inch 1018 cold roll and has a spigot on it that passes thru a seal in the top of the drive tube, I left as little clearence as possible so that sand would not work in between and get in the top bearings.
and a not so great video of it in operation mixing some new sand
