Mech Cryogenic Grinding | PDF | Cryogenics | Mill (Grinding)
CRYOGENIC GRINDING TECHNOLOGY For pulverizing many materials, cryogenic grinding technology increases productivity and lowers power costs. Many elastic or "soft" materials are very difficult to pulverize, requiring long cycle times and high energy consumption. This combination decreased productivity and increased costs unnecessarily.

20–40%. To cut costs even further, mechanical refrigeration can replace some or even all of the liquid nitrogen – and in the latter case that means total operating costs, including capital charges, of just 15–20% of the cost of an equivalent cryogenic mill."

Size reduction Archives : Powder and Bulk Engineering
December 16, 2019. Cryogenic grinding permits heat-sensitive, thermoplastic, and elastic materials to be economically ground to very small particle sizes. The cryogenic process actually embrittles a material prior to size reduction and controls heat buildup in the grinding equipment. The result is high product quality and system productivity.
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.
