Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% EFFECT OF BALL SIZE DISTRIBUTION ON MILLING PARAMETERSA.1 Batch grinding tests on single ball sizes 82 A.1.1 Particle size distributions obtained using 30.6 mm balls 82 A.1.2 Particle size distributions obtained using 38.8 mm balls 83 A.1.3 Particle size distributions obtained using 49.2 mm balls 86 A.2 Batch grinding tests on mixtures of balls 88 Variables in Ball Mill Operation | Paul O. Abbe®A Slice Mill of 72" diameter by 12" wide would replicate the result of a normal production, mill 72" in diameter as 120" long. A Slice Mill is the same diameter as the production mill but shorter in length. Click to request a ball mill quote online or call 630-350-3012 to speak with an expert at Paul O.
