Select section below corresponding to the 2nd letter in your serial number to identify the type of Cincinnati machine.
Cryogenic milling, or cryo milling, is the process of using liquid nitrogen to lower the temperate of the material and or the milling process. AVEKA ‘s cryogenic hammer mills can typically reduce the particle size from small pellets down to the 100s of microns.The effect of grinding media performance on milling and operational behaviour was demonstrated under different selected conditions of calcium carbonate slurry milling.
