Ball milling (solid-state synthesis) is one of the most important processes used in industry to synthesize nanomaterials, and is also called mechanical alloying or attrition. This method is based on a top-down approach, like self-assembly of molecules and reducing the size of the larger particles.
Jun 15, 2012· As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). 2. The powder of a material is taken inside the steel container.

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.
Small ceramic, glass or metal beads are agitated inside the mill chamber to aid particle size reduction through impact and energy input while the dispersion is pumped through the mill. Bead mills are one of the most effective methods for processing fine particles into sub-micron or even nanometer size range.
