  • Ball Milling | Material Milling, Jet Milling | AVEKA

    Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion the particles in between the media and chamber walls are reduced in size by both impact and abrasion.

  • Effect of mill type on the size reduction and phase ...

    Sep 29 2015 XRD and TEM studies confirm that the planetary ball mill causes phase transformation to the less desired α-Alumina resulting in a notable decrease in surface area from 136.6 m 2 g to 82.5 m 2 g as measured by the BET method. This is consistent with the large shear stresses under high shear rates prevailing in the planetary ball mill when compared to the other mill types.
