The effects of cryogenic cooling on the grinding

2020-8-1  Cryogenic cooling (utilizing liquid Nitrogen or CO 2) can be a very effective method for the reduction of tool loading and improving the grinding process due to its high cooling rate. Using cryogenic cooling, the cutting action is more than sliding and plowing. Compared to liquid Nitrogen, CO 2 gas is more economical and also more user-friendly.

Cryogenic Grinding Presentation Union Process

Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits. Attritors can generally grind to finer size particle size range than impact or hammer mills by combining the advantages of cryogenic temperatures with both impact and shear forces inherent to high energy internally agitated ball mills.
