Process engineering: Particle size reduction

Some of the more difficult materials to mechanically process are plastics, rubbers and fibers because they deform, but do not fracture, when struck. One solution is cryogenic milling, in which liquid nitrogen or carbon dioxide is injected with the feed to a hammer mill. The extreme cold makes plastic materials brittle enough to fracture easily.
