Particle Size Reduction Disputanta VA Ancos

Why use cryogenic grinding: Some polymers require the use of cryogenic grinding in order to reduce the particle size. Given certain polymer properties, some materials do not behave in a way that is necessary to achieve desired particle size reduction results without being chilled. For example, crystalline materials would melt from the friction of the grinding process if they were not cooled ...

CRYOGENIC GRINDING AND IT’S APPLICATIONS

Cryogenic grinding usually starts with chips or a fine crumb. This is cooled using a chiller. The final product is a range of particle sizes which are sorted and either used as is or passed on and further size reduction performed .The cryogenic process produces fairly smooth fracture surfaces. Little or no heat is generated in the process. This results in less degradation of the rubber. In ...
