This malt mill served me trouble-free in the homebrewshop for its entire run.
Hand built by Maltmills.com, it features a 1/3HP farm grade motor, three rollers and a large hopper that holds just shy of 50lbs of malt.

I am not sure if the mill gap is adjustable as I’ve never messed with it. It puts out a perfect grind with barley malt and wheat. I will investigate if adjusting the gap is important to you.
Will chug through a full bag of malt in about four minutes.
