Planetary ball mills are the most popular mills used in scientific research for synthesizing MgH 2 nanopowders. In this type of mill, the ball-milling media have considerably high energy, because milling stock and balls come off the inner wall of the vial and the effective centrifugal force reaches up to 20 times gravitational acceleration.

Working Principle : A Planetary Ball Mill consists of at least one grinding Vessel witch 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 it’s own axis as well as about the axis of sun wheel.

Functional Principle The grinding jar is arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2. The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.
