The main cooling source for cryogenic grinding is liquid nitrogen. The material is brought from a hopper to the liquid-nitrogen-cooled area The material is cooled rapidly because of the extremely cold temperature of the liquid nitrogen. Once cooled, the material becomes very brittle, and grinds efficiently.
Dec 22, 2016 The grinding media as well as the interior surfaces of the mill can be lined with abrasion resistant materials suited to the material being ground. In some cases, it can even be the material
Other materials have also been used both for the planar grinding stage or, afterwards, to replace SiC paper.
