I have a Barley Crusher Malt Mill, bought it new in 2008. For the last 5-6 months it's been jamming or "cavitating" about 10 times during every 20+ lbs batch of grain I mill. For those who don't know the mill, only one of the two rollers is driven (in my case by a cordless drill running around 300 RPMs) and the other is supposed to spin when the grain gets between the rollers. But it keeps stopping and you have to bang or shake the mill a lot to get it going again, and usually once per batch of grain I have to dump it out and clean it out. I have it running at the factory gap setting.
Any suggestions on how to get this fixed? I blast it out religiously with high pressure compressed air after each use so it is externally clean. Is there oiling or something to do internally? Or a way to make it not jam up? Or is it time for a better mill of new & improved design?
