  • Ambient vs. Cryogenic Rubber Grinding

    Cryogenic grinding – starting with rubber that has been coarse ground to two-inch minus, it can produce a fine grind, ¼ inch minus to 30 mesh, in fewer steps at a rate of 4,000-6,000 pounds per hour. In this method, liquid nitrogen is used to freeze the rubber, which is then "shattered" as it passes through a hammer mill.
