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.
