To produce very fine particles of 100 nm or less (nano-scale grinding) by wet grinding, friction rather than impact is required. This is achieved by using a large number of small grinding balls which have a large surface and many friction points. The ideal filling level of the jar should consist of 60 % small grinding balls.

where C is the density of the grinding grain and r is the width-to-thickness ratio of the chip. In Malkin's model, the maximum UCT was based on the uniform location distribution and grain size. Under these assumptions, the calculated UCT was estimated to be 0.2~1 μm [], 0.6 μm [] or 0.3~0.98 μm [], and less than the critical depth of plowing …
of the ball mill would be of great interest. Accordingly, the aim of this paper is to identify which dimen-sionless numbers must be kept constant in order to reproduce the results obtained in a laboratory ball mill at the industrial scale. Such scaling criteria are provided by an exhaustive dimensional analysis applied to the ball mill.
Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).
