Cryogenic grinding avoids the plastic deformation due to thermal loading by dropping the temperature developed in the grinding zone which will help to maintain the compressive residual produced as a result of plastic deformation caused due to mechanical loading and thus increases the number of cycles to cause a failure in the material samples.

Application of cryogenic grinding as well as its duration significantly increased the amount of bioactive molecules extracted from pumpkin seed cake as well as extracts antioxidant activity. Major increase was determined for phytosterols and protochlorophylls which were 2 and 2.5 fold higher respectively in pumpkin seed cake samples ground with cryogenic cooling during 12 min.
Cryogenic grinding is a process where thermally sensitive and elastic substances are successfully processed by cooling with liquid nitrogen. The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process.
Cryogenic grinding was required for accurate qualitative and quantitative analysis of additives such as antioxidants using HPLC and INOC-Test. The FreezerMill iently reduced these samples to particle sizes of less than 500 m in less than 15 minutes without thermal degradation.

The test results indicate that using a knife mill with a 1 mm screen perforation along with cooling the feed to cryogenic temperature significantly improves the efficiency of the process. The grinding products were characterised by the highest release level of the useful substancemetals in the free state.

Aug 01 2008 The efficiency of a grinding step was evaluated using RSDs and homogeneity factors H-factor. For cryogenically grinded samples RSDs were detected about 4 and H-factors on 10 what is acceptable for the analytical purpose. The results for grinding with an agate mortar as well as a coffee grinder were quite unsatisfactory RSDs in tens percent.
System Overview. The Cryogenic Grinding system is built around a chest freezer which maintains an average operating temperature of -60 degrees. It has the capacity for 96 scintillation input tubes and 576 X 1.4ml Micronic output tubes. Stainless steel ball bearings along with the sample are placed into the input tubes before they are frozen and manually placed into the freezer.
