Ball Mills - an overview ScienceDirect Topics

Planetary ball mills are the most popular mills used in scientific research for synthesizing MgH 2 nanopowders. In this type of mill, the ball-milling media have considerably high energy, because milling stock and balls come off the inner wall of the vial and the effective centrifugal force reaches up to 20 times gravitational acceleration.

Mechanochemically assisted preparation of NbB2 powder ...

2006-1-1  A powder mixture of Nb-B (1:2) was milled using milling media of different sizes in a planetary ball mill, and NbB 2 was mechanochemically prepared. When the mixture was milled with 5 mm diameter balls, NbB 2 started to form in 20 h and the single phase NbB 2 was obtained in 50 h. The time required for the NbB 2 formation and the single phase decreased with the increase in the ball size.
