    1. Introduction. Due to their high energy density planetary ball mills are especially suited for fine and ultra-fine grinding of hard and brittle material down to the nanometre size range,for mechanical alloying and for mechanochemical reactions (among others,,,).In comparison to ball mills and vibrating mills higher stress intensities can be generated due to the centrifugal field.
