InSitu Acquisition of Grinding Parameters - fritsch

With earlier planetary ball mill designs, the kinematics of the mills were always perfected to ensure an optimal launching point for the grinding elements as learned from the conventional ball mills. The grinding drum of a ball mill functions in earth's gravity field, whereas the movement of a ball in the planetary ball mill is due to the superposition of various centrifugal and coriolis forces.

In situ production of Al–TiB2 nanocomposite by double

2009-5-1  An in situ Al–TiB 2 nanocomposite was synthesized by mechanical alloying (MA) of pure Ti, B and Al powder mixture in a planetary ball mill. A double-step process was used to prevent the formation of undesirable phases like Al 3 Ti intermetallic compound. In the first step, a powder mixture was tailored to obtain nominal Al–90 wt% TiB 2 composition and the second step involved the addition ...
