Planetary ball mill is a very often used machine for mechanical alloying, especially in Europe. Because very small amount of powder (for example, as little as a few grammes), is required, the machine is suitable for research purposes in the laboratory.
The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and therefore short grinding times. The PM 100 CM is a convenient benchtop model with 1 grinding station. It operates in centrifugal mode mode, which leads to a more gentle size reduction process
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
