Cryogenic grinding of rubber

Cryogenic processing refers to the use of liquid nitrogen to freeze tyre chips or rubber particles prior to size reduction. Most rubber becomes brittle or "glass-like" at temperatures below -80°C. Typically, the size of the feed material is a nominal 2-inch chip or smaller. The material can be cooled in a tunnel style chamber, immersed in a
