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 .
WhatsAppعرض المزيدADVANTAGES OF CRYOGENIC GRINDING Higher material removal rate can be achieved. Tool wear and tear is minimized to a great extent. Grinding forces are reduced. Cryogens act as coolant and hence the effects of overheating of the tool and work piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.

WhatsAppعرض المزيدGrinding is a subset of cutting, as grinding is a true metalcutting process. Each grain of abrasive functions as a microscopic singlepoint cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

WhatsAppعرض المزيدCryogenic grinding is a method of powdering herbs at subzero temperatures ranging from 0 to minus 70°F. The herbs are frozen with liquid nitrogen as they are being ground. This process does not damage or alter the chemical composition of the plant in any way. Normal grinding processes which do not use a cooling system can reach up to 200°F.
WhatsAppعرض المزيدCryogenic 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.
