Planetary Ball Mill 911Metallurgist

The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.

Effect of Ball Milling and Crystallizing on Magnetic

Magnetic properties increase with milling time. Milled for 25h and crystallizing at 700C for 30 minutes, samples have the best comprehensive magnetic properties (remanence, coercivity and magnetic energy product). To obtain nanocomposite permanent materials with high magnetic properties, it is necessary to combine ball milling with crystallizing.
