The auger not only transports the grinding media, but also mixes with liquid nitrogen for greater cooling efficiencies. The liquid nitrogen, a cryogenic fluid with a boiling temperature of –196 0C absorbs heat from the material and vaporized to a gaseous state. The nitrogen gas exits the system conveying the process heat away from the process.

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.

This type of process may be completely adequate for many labs, but some researchers are under pressure to process hundreds if not thousands of samples daily. Therefore, the level of throughput needs to be considered in designing a scheme. Harvesting Samples

Study on ambient and cryogenic grinding was performed to test the novelty of cryogenic grinding and pin point the drawbacks of a mbient grinding. Comparative study had shown that ambient grinding need more power (8.92%) and specific energy (14.5%) than cryogenic grinding. Particle size anal ysis had shown that cryogenic grinding produced coarser particles.

Cryogenics Standards. Precisely how cold a material must be to be considered cryogenic is a bit ambiguous among the scientific community. Now, according to the U.S. National Institute of Standards and Technology (NIST), cryogenics relates to materials studied in temperatures below -180 °C (93.2 K), which is a temperature above which popular refrigerants …

Cryogenic processes can also use "dry ice" (i.e., solid CO 2) or compressed CO 2 to embrittle the feed material prior to grinding. However, like liquid nitrogen, a great amount of energy is required to compress the CO 2 gas into "dry ice". These additional costs tend to limit the use of cryogenic grinding to high value materials.

ADVANTAGES OF CRYOGENIC GRINDING Higher material removal rate can be achieved. Tool wear and tear is minimized to a great extent. Grinding forces are reduced. Cryogens act as coolant and hence the effects of overheating of the tool and work piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.
