Stirred mill technology dates back to 1928 where the idea to use an agitator and spherical grinding media was presented The year 1948 saw the successful application of DuPont s sand mill for pigment grinding Subsequent years have led to the development of different types of stirred mills spanning a number of industries that require fine and ultrafine grinding In the context of
vibratory and ball mills with Si3N4 media was examined The rate of particle size reduction and the change in the chemical composition of the powder were determined in order to compare the grinding efficiency and the increase in impurity content resulting from mill and media wear for each technique Attrition and vibratory milling exhibited rates of specific surface area increase that were
