Why is the grinding efficiency of the ceramic grinding bowl on a planetary ball mill higher than that of a common grinding machine

09/01/2023 09:43:46

The reason why ceramic ball mills on planetary ball mills perform well in terms of grinding efficiency is closely related to their unique structure and working principles.

The main reasons:

1.Multidimensional motion: The planetary ball mill uses grinding balls fixed to a turntable to cause complex, multidimensional movements inside the mill bowl when they are subjected to rotating and autorotating motion at various speeds. This multidimensional movement not only enables more uniform mixing of the grinding medium and samples, but also enables more efficient collisions and milling processes, thus increasing grinding efficiency.

2.High collision energy: The collision energy between balls and between balls and samples in planetary ball mill cylinder is higher, as the combination of multidimensional motion and high speed rotation, larger impact and shear forces are produced, which can accelerate grinding and mixing processes and improve grinding efficiency.

3.Small sample particle size: Planetary ball mills are suitable for grinding small particle samples, because with multiple dimensions of movement, small particles are able to undergo more substantial impaction and milling to reach the required fineness level of polishing.
