Dec 17, 2020 · This high energy ball mill agitates the charge of powder and balls in three mutually perpendicular directions at approximately 1200 rpm. Ball velocities in such shaker mills are high, o m/s. A given reaction, such as amorphization, can typically take place an orderofmagnitude faster in the Spex mill than in the usual vibratory or attritor mill.

The extremely high centrifugal forces of the mill result in very high pulverization energy and therefore short grinding times. This ball mill is suitable for longterm trials and continuous use, and it has two different grinding modes (dry and wet). Material feed size is <10 mm, and final fineness is <1 μm and for colloidal grinding < μm ...

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.

The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.
