Temperature of the milling balls in shaker and planetary mills
The ball temperature remains below 100 °C in a SPEX 8000 shaker mill and it is cooler when flat-ended rather than round-ended vial is used, although the milling intensity, as measured by the mechanical dose rate, follows the opposite trend. Temperatures over 200 °C are typical in planetary mills operating at similar milling …

SPEX SamplePrep
In this study various nano-crystalline materials were produced using a ball mill (8000M Mixer/Mill®, SPEX SamplePrep; equipped with alumina and zirconia vials). Ball milling is particularly suitable for this task as it is easy to use and allows the grinding of a relatively large amount of material as well as a large variety of different materials.
