Planetary Ball Mills

A ball mill is a large equipment that grinds down the material fed into it to give a coarse end product with smaller particle sizes. One of the primary applications of ball mills is in ore dressing.

Planetary ball mills, on the other and, are relatively much smaller and are used in labs to grind down samples into fine powders. It uses a combination of forces to grind the sample into very small particle sizes. Hence, planetary ball mills are known for their ability to use high energy forces to obtain fine particle sizes in a very short time.

The planetary ball mill has various grinding jars with balls in it, that are arranged on the periphery of a wheel called the “sun wheel” such that the axes of the sun wheel and the grinding jars are parallel to each other. The direction of rotation of the jars may be the same or opposite to the direction of rotation of the sunwheel. The name “planetary” stems from the fact that the rotation of the grinding jars on their respective axes are similar to the rotation of the planets on their axis and the larger rotation of the grinding jars on the sun wheel with respect to the axis of the sunwheel itself, is similar to the revolution of the planets around the sun in the solar system.

The force that grinds the material is a combination of the friction between the sample material particles within the grinding jar, the balls in the grinding jar and the sample material, the centrifugal force due to rotation of grinding jar as well as the forces due to the rotational movement of the sun wheel.

Planetary ball mills can be for wet grinding as well as for dry grinding to prepare samples for lab usage. They find their applications in the grinding of a wide variety of materials that range from glass, shells, wood pieces, and metals.

Planetary ball mills need effective vibration isolation to keep them working at their best. For this, many manufacturers use the Free Force Compensation Sockets (FFCS) methods that are based on D’Alembert’s principle to compensate for vibrations through small circular movements of the machine. This in combination with a stable anti vibration surface to mount the planetary ball mills equipment can be a valuable tool in conserving energy and improving the performance of planetary ball mills in your lab or work place.
