Abstract

Metal particles which are ductile at ambient temperature are comminuted by being passed through a first impact mill, e.g. a vibratory ball mill (2), at ambient temperature to increase their length to thickness ratio, embrittled in a precooler (4), and then comminuted in a second impact mill, e.g. a rotary impact mill (6). <IMAGE>
