Cylindrical zirconia or stainless-steel grinding media should be used for effective grinding of the powder. Union Process Attritor Mill. The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area.
Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20 to 50 of the mill volume, or to the center line. Approximately 30-40 of the ball charge will be void space.
