With more than 100 years of experience in ball mill technology Metsos ball mills are designed for long life and minimum maintenance They grind ores and other materials typically to 35 mesh or finer in a variety of applications both in open or closed circuits.
A smallbatch ball mill Lets start with the assumption that a beginner pyro hobbyist needs a relatively small ball mill that they either dont know how to or dont want to make one for themselves and that they want that mill to be affordable If I was back in those shoes this is what I would do.

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.
Starting the mill remotely either by plugging in a 100 extension cord that runs to it or by setting the mill time on a timer prevents you from standing next to it while it is running Notice the timer in the photo of my doublebarrel mill and in the photo below.
