A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.

For lactose granules, data showed that fine particle sizing occurred at 9000 RPM, while only larger particles were reduced at 1000 RPM, 4000 RPM, and 6600 RPM. Large particles were reduced much more effectively as speed increased from 1000 RPM to 4000 RPM, however less change was seen from 4000 RPM and 6600 RPM.

Abstract Size reduction is the operation carried out for reducing the size of the bigger particle into a smaller one by external forces. This reduction in size is done by using ball mill. In the experiment, the stone weighs about 300g and mix with two handhelds of grinding ball into the ball mill. The speed control knob is adjusted each at 40 rpm and 80rpm.

As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice. Once the particles are too fine for image analysis - roughly several microns - they are best analyzed by laser diffraction instruments such as the LA-960 and LA-300.
