The planetary principle provides a high energy input to produce particle sizes down to the submicron range. These are the perfect conditions for mechanical alloying and colloidal grindings. MECHANICAL ALLOYING PAGE 10 High energy ball mills and planetary ball mills provide the required kinetic energy for mechanical alloying.

Planetary Ball Mill Working Principle. Planetary Ball Mills consist of several cylindrical grinding jars (positioned on the sun wheel as shown on the figure) which are filled with loose grinding balls. Two superimposed rotational movements move the grinding jars: Like in a planetary system the grinding jar rotates on a orbit around the centre.

IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
