The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. The motor was mounted using screws on only one side, which were deliberately left loose.

2 GEARLESS MILL DES The gearless mill drive eliminates ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
