size-reduction mechanism of the mill. However, because the feed material typically cannot be modified, particle shape is strongly influenced by the type of grinding mill selected. Characterize the feed material To determine the type of mill you will need for your application, gather information about the nature of the mate-rial to be ground.

Practical 1 : Ball Milling | TF Lab 1

In cutter mill, size reduction occurs by fracture of particles between the two sets of knives. In hammer mill, size reduction occurs by impact, by four hammers attaching on a central shaft. In end-runner and edge-runner mills, compression is carried out on a small scale in a mortar-and-pestle form.
