Cryogenic grinding involves the use of liquid nitrogen to chill pellets in advance of the grinding process. Once cooled, the pellets proceed through a mechanical mill. The use of liquid nitrogen to chill the pellets enables more effective size reduction. Cryogenic grinding can be mechanically difficult, requiring expertise to manage moisture ...

For this purpose, the grinding experiments were performed under two different grinding environments such as dry and cryogenic conditions using a cubic boron nitride (CBN) grinding wheel. The results revealed that surface roughness could be reduced by about 87% under cryogenic condition over dry grinding.

The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml.
