What is Cryogenic Milling? Cryogenic milling, or cryomilling, 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. Cryomilling can be used for:
MiniMobile Gold Processor. One of our unique designs combines a sluice connected directly to the hammer mill outlet. The hammer mill is a standard 16″ x 12″ powered by a 22 hp gasoline engine and will accept a feed size up to 21/2 inches. This makes for a portable and cost effective small production machine or robust sampling system.
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
