Cryogenic grinding: an independent voice
cryogenic grinding processes. "I am sure cryogenic grinding is a growing market, especially in areas such as rotomoulding materials, hotmelt adhesives, powder coatings and recycling," says Bertling, "and this facility will provide independent advice, with no bias towards particular manufacturers." If the economic gains to be had

Grinding spices: How does cryogenic grinding work? Mill cooling uses liquefied cryogenic nitrogen (LIN) or liquid carbon dioxide (LCO2) to significantly reduce the temperatures of the feed material. Cryogenic grinding with in a paddle screw cooler freezes .
Cryo Pumps: Dry Run Seal, Damaged Seal?
· We have some problems with our cryogenic pump (model DSM 230, Vanzetti) two times in a row. The problem is: we experienced a damaged seal (see photo's). According to the company who has been repairing the pump, this is because there is not enough LIN (liquid nitrogen) to lubrie the seal. (The one part on one photo is the steady part, which ...
The effect of cryogenic grinding and hammer milling on the ...
· Cryogenic grinding. Samples of black, white, and green peppercorns were ground separately using a cryogenic grinder (SPEX 6870; SPEX Metuchen, NJ). First, peppercorns were prefrozen in a liquid nitrogen bath (−210 to −196 °C) for 10 min and then pulverised with a magnetically driven impactor at 10 s −1 in the liquid nitrogen bath.
