Comminution is the result of a combination of friction and impact at high energy. Planetary ball mills with a fixed transmission ratio are optimised for a single grinding process only.
Chat OnlinePlanetary 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.
