The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material (feeders) and the system for discharging the output product The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0 5 to 3 5 The starting material can be loaded either through a spout feeder or by

Ball mills can be used to further break down or refine a single material or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes Ball mills basically function like a mortar and pestle but on a much larger scale
