Cryogenic Grinding | Linde (former AGA) Industrial Gases

In order to grind tough and elastic materials with a high throughput into fine powder, an efficient cryogenic cold grinding system is required. The feed material must firstly be cooled with a suitable refrigerant such as e.g. liquid nitrogen to a defined temperature usually below the glass transition or softening temperature to cool.

the rubber or tire chip. The cooled rubber is ground in an impact type reduction unit, usually a hammer mill. This process can be used to produce fine micronized rubber powder ranging from 30 mesh size (595 microns) to 300 mesh size (50 microns). Micronized rubber produced by cryogenic process behaves like reinforcing filler in a rubber compound.

Cryogenic Fine Grinding of Rubber from Used Tires Superfine powdered rubber can be manufactured efficiently using a cryogenic process. Liquid nitrogen is employed to cool the feed granules below their glass transition temperature before they are pulverized with counter-rotating pin mills.

Cryogenic grinding of rubber - kpsimpex

Cryogenic grinding can achieve a very fine level of grind as most hardy materials tend to become brittle when cooled with liquid nitrogen. To produce crumb rubber, it is necessary to reduce the size of the tire shred or chip. This is accomplished by techniques called cryogenic grinding. Cryogenic processing refers to the use of liquid nitrogen ...
