The differences between the two are summarized below. Dry pulverization is used in a wide range of fields because of its features. The size of pulverized products is generally reduced to micron level. In some cases, pulverization to submicron level is possible, but there are problems, such as aggregation and difficulty of collection.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
