involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
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.
Pin mills are used to reduce the size of medium- to low-density materials such as talc and clay. Pin mills use centrifugal forces to smash large particles against pins. Equipment Design A colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins.
