Likely it came from the fact that "mill" got applied to some of the oldest of man-made mechanical contraptions (another one of those words...). Charles Babbage designed a complex automatic calculator (almost, but not quite, a computer!) in 1840's? and he called the guts of it, that did the intricate addition etc, "the mill", numbers were the grist, got milled, then output. If you track the earliest use of (engine, motor, mill, contraption,...) in English, you'll find they got swiped from greek or latin probably 300 - 400 or more years ago.
