Please note: For the Planetary Micro Mill PULVERISETTE 7 classic line, you require at least 2 grinding bowls of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

  • Additional Information

    Grinding balls with diameter 3 mm and smaller must be weighed out. The above table provides you with the necessary weight to be included per grinding bowl.

    The specified ball filling per bowl is the minimum quantity and should possibly be increased depending on the material properties. The useful capacity depends on the type of material. In exceptional cases, the number of grinding balls can be reduced by up to 15 %. However, increased abrasion should be expected. In general, smaller grinding balls achieve finer grinding results.

    In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used.

Please select 2 grinding bowls, which are offered in the sizes 45 ml and 12 ml to perfectly match your sample volume. The useful capacity of the grinding bowls can be found in the selection aid.
For the best grinding results in each individual case, all grinding bowls are available in 7 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion.
