A Planetary Ball Mill consists of at least one grinding Vessel which is arranged eccentrically on a sun Wheel / Rotating table. When the sun wheel rotates about its axis, the vessel follows planetary motion i.e. it rotates about its own axis as well as about the axis of the sun wheel. The direction of rotation of the vessel is opposite to that of the sun wheel, this imparts very high energy to the balls to collide with one another during high-speed movements causing very fast grinding and mixing of material(s) in the vessels to a very high fineness up to 1 Micron depending upon the physical characteristics of the material, number and size of balls, time and speed selection.
