The effect of milling temperature on the amorphization of mechanically alloyed Cu 30 Ta 70 has been investigated in 1991 by Lee et al. [45] In their experiments, they ballmilled the elemental powders of Cu 30 Ta 70 at two different controlled temperatures of 37°C and 200°C for 100 h under the same milling conditions. They realized that ball milling at 200°C leads to the formation of an ...

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
