Gear - Wikipedia
The segmental gear, which receives/communicates reciprocating motion from/to a cogwheel, consisting of a sector of a circular gear/ring having cogs on the periphery, was invented by Arab engineer Al-Jazari in 1206. The worm gear was invented in the Indian subcontinent, for use in roller cotton gins, some time during the 13th–14th centuries.

Metal lathe - Wikipedia
A metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range of materials.
Fine Grinding - an overview | ScienceDirect Topics
The general guidelines for high performance grinding require a 40–60 mesh for rough grinding; a 60–100 mesh for finish grinding; and a 100–320 mesh grain for fine grinding. When selecting a particular grain size one must consider that large grains allow the user to remove material economically but make the material easier to machine by ...

How I built a quick and easy home-made ball mill
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.
