Planetary Ball Mill BM40 & BM6Pro
Planetary Ball Mills are suitable for grinding (dry/wet) and mixing some soft, hard, brittle and fibrous samples, which are used wherever the highest degree of fineness as customer required, as well as the grinding result is reproducible.
Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding.

When the Planetary Ball Mill starts, the motor drives the common sun wheel to move, while the grinding jars, which are located on the sun wheel, turning around its own axis.
The direction of the 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 movement, the so-called Coriolis forces. Under this interaction, the grinding balls release high dynamic energies.
The samples are constantly impacted by the grinding balls, and rapid crushed by the friction of the grinding jar’s inner wall at the same time.
The Planetary Ball Mills have 1.2 and 4 grinding stations as option. the parameter can be set according to the sample property freely. Wide kinds and high quality grinding materials are available for choice. Grinding balls of different quantities and sizes can be combined flexibly to meet personalised special crushing and grinding requirements.
When the Planetary Ball Mill is in operation, extremely high impact energy is produced between the grinding balls and the grinding jars, so it can finish the grinding of the sample in a very short time.
The working principle of the Planetary Ball Mill is based on the relative rotation of the sun wheel and the grinding jar. The speed ratio influences the input energy and results of grinding directly. We can customise the speed ratio from 1:1 to 1:-3.5 as customer requirements.
