Effect of Ball Milling on Powder Preparation by Mechanical Methods

Abstract:

In the milling process, the particles experience mechanical stresses at their contact points due to compression, impact, or shear with the mill medium or with other particles. The rate of grinding depends on a number of factors, including the mill parameters, the properties of the grinding media, and the properties of the particles to be ground. SEM photomicrographs show that the mean sizes of final refined powders are about 200–400 nm, and are quite uniformly distributed by wet ball milling, so the quasi-nano powders are very suitable for sintering.
