How Ball Milling Of Particles Work

Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Mill (grinding) Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Preparation of iron oxide nanoparticles by mechanical milling

In the initial stage of milling, the fully crystalline brittle particles tend to break easily but as milling progresses the particles fall into the ductile range and mainly undergo plastic deformation (Palaniandy and Jamil, 2009). This phenomenon can be observed as there is little change in particle crystallinity as milling progresses.
