Detailed Description

Planetary Ball Mills are used wherever the highest degree of fineness is required. In addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying. The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and therefore short grinding times. The PM 100 is a convenient benchtop model with 1 grinding station. Operates with 2 sets of grinding jars and aeration lids and zirconia grinding balls.
