    My modified ball mill using brass ballsposted in Pyrotechnics Hello forum. Sometimes ago I ordered this ballmill from Pyrocreations It has an internal barrell diameter of 103mm and a capacity of 0.8l. The working voltage is 120V but since I live in Italy I was forced to buy a transformer 120 -> 220V The first issue of this very cheap ballmill was the rotation only 45 RPM

  • Ball Mill Operating principles components Uses

    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 3050 of the mill volume and its size depends on the feed and mill size.
