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 ...

Cryogenic grinding is necessary for materials with a low melting point or those that are very tough and difficult to grind fine without extra cooling. Fine grinding/pulverization/cryogenic grinding is available for 8 200 mesh or 2000 75 microns and finer for friable materials.

Cold Grinding, Cryogenic Milling. Cooling of heat sensitive materials with liquid nitrogen during the grinding process prevents their temperature from rising during the mechanical grinding. The usual heating due to the grinding process is prevented which eliminates material melting and sticking.

Industrial CryoTech provides the revolutionary ICEFLY cryogenic cutting system to the machining industry. By cooling the cutting zone to cryogenic levels, ICEFLY increases cutting speeds, extends tool life and eliminates whole steps in the cutting process.

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 counterrotating pin mills.

Cryogenic Milling with the Pin Mill GSM 250. The Pin Mill GSM 250 is a cryogenic grinding system of the highest quality. The milling plant is made of stainless steel. This also applies to the other system periphery such as the cooling screw conveyor, the filter, etc. Small particle sizes of up to 20 µm (microns) achievable.

Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling.

The Cryogenic Homogenizing System is a miniaturized mortar and pestle system that combines the effectiveness of manual grinding with the convenience of a handheld homogenizer. The Cryogenic Homogenizing System is designed for processing multiple small samples,, less than grams and most effective at
