A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
What is Cryogenic Milling? 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. Cryo-milling can be used for:
