MECHANICAL ALLOYING IN PLANETARY MILLS OF HIGH

It is known that planetary mills possess higher energy density and provide stronger mechanical impact on materials than other milling devices. Planetary mills are characterized by higher pres-sure on particles and higher energy density than attritors, vibro-mills, jet mills and disintegrators [7]. Earlier only laboratory planetary mills were in use,

Mechanical alloying and reactive milling in a high energy ...

10-06-2009  Note that the models proposed earlier for mechanical alloying in planetary mill , ignored rolling ball motion as affecting the refinement or phase changes in the powder being processed. In those models, the refinement was considered as a function of the overall energy transfer from the balls to powder as a result of ball collisions, analogous to the situation for the shaker mill.
