Abstract

The metal powder of iron and tungsten are made by high energy mechanical ball mill, the structure of vibration mill and it's crushing principal are briefly discussed. The size distribution and specific surface area of iron and tungsten powder are analysed. The effect factors, including sample nature, milling time, milling intensity,ratio of ball to sample which affect the high energy ball milling process,are discussed.
