HP=HP per ft of mill length. W=Weight of grinding charge and material per ft of mill length. C=Distance in feet from center of mill to the center of gravity of the grinding media. a=Dynamic angle of repose of grinding charges, usually 43° for dry grinding slow speed ball mill, 51° for normal ball mill speeds. *The...
Ball Mills vs Rod Mills
The average particle is subjected to an action similar to many sets of rolls in series, before it is discharged. Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load.
Grinding Balls & Rods
The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball …
