Been following this post and got to thinking, how much malt will a crusher mill?
So I checked my brewing report for mine and My "Barley Crusher" has gone through over 2300#s. The roll bushing have no more wear than when it was new, and I do check it every 5 batches or so. I have taken it completely apart for cleaning once last year, the second roller was gumming up a little in the bushings, but it cleaned out and has worked well since then.
You could only guess how much one in a LHBS runs through.
