I would be very grateful if someone could provide some info (or where I could get it) about the use of CO2 in cryogenic grinding. All the info I've found about cryogenic grinding deals with the use of liquid nitrogen as the cryogenic agent. We have performed some tests on our product that show that CO2 would be enough to achieve an efficient grinding. Therefore, I need some basic data such as typical consumptions, handling, operation conditions, etc. Thanks in advance.
