I recently came across this in BYO"

My only remedy right now is to use the torque setting on my drill and reduce the trigger.
Might explain a few points of efficiency and some individual differences between brewers with identical settings on the same mill.
A common drill motor can motorize most mills. The problem with this approach is, while it works, it simply works too fast. Optimum roller speed for small homebrew mills is 150200 rpm. Drills and most AC motors run at 1,750 rpm (U.S. 60 cycle AC.) The answer is to use pulleys and belts or an expensive gear reduction motor to run your mill more slowly.
