Grinding mills include oscillating and vibration mill, attrition jet, planetary mills, all of which are known as high energy mills [4]. Among all, planetary milling is the most simple and widely used plastic deformation method through which one can achieve extreme refinement in the structure of materials in .
The planetary mixer/mill is capable of emulating ball mills of conventional design, simulating the types of stress entailed and thus reproducing or optimising grinding processes. Due to the high flexibility available for selecting the grinding parameters, it is possible to achieve results unattainable with any other ball mills.

This study aims to examine Book I of the Planetary Hypotheses in The Planetary Hypotheses is related to and directly builds upon many of Ptolemy''s other works, including: the Canobic Inscription,7 Handy Tables,8 Optics,9 Harmonics,10 and the The Planetary Hypotheses is an astronomical work, which was written after
Disk mills are used for mechanical refining, of wood pulps and are utilizing mainly shearing and attrition forces. Szego Mill The Szego Mill used in this study is a planetary ringroller mill which shown in Figure It has a simple structure which consists principally of a stationary, cylindrical grinding surface
Planetary Ball Mill. The PM 100 CM operates with a speed ratio of 1:1 (centrifugal mode). The centrifugal forces produced by the rotation movement the sample and the grinding balls against the inner wall of the grinding jar, where size reduction takes place primarily by pressure and friction.
