In mechanical milling, work materials are placed together with some milling balls in a vial. The work materials and the balls, which are also known as charge materials, are then moved in the vial upon the motion of the vial. The reason to move the charge materials is to bring them in colliding positions.

Ball milling: The main principle of mechanical milling can be described as the exploitation of high energy grinding to reduce the particle size. In general, the high energy ball milling route is used to yield nanosized particles, especially for metallic PNPs synthesis [45]. To initiate the size reduction process, bulk samples of the NPs are ...
The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.
