Cryo grinding is not an efficient milling technique for materials that are already brittle at ambient temperatures, or ones that will not embrittle when transitioned to cryogenic temperatures. These include thermoset resins, epoxies, brittle inorganic compounds (ceramics, glasses, and minerals), and fibrous materials (carbon and fiberglass). 2.

CRYOGENIC GRINDING. Abstract Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size In physics, cryogenics is the production and behaviour of materials at very low temperatures.. Cryogenic grinding involves cooling a material below its embitterment
