Ball Mill Design/Power Calculation - 911 MetallurgistMar 17, 2017 . The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk.Best way to determine the ball-to-powder ratio in ball-milling?To really choose, I guess it depends on the material and your mill (vial, RPM, media, filling volume). I.e. Si80Ge20 is easily alloyed in the high energy SPEX mill. But thermoelectric materials like skutterudites with a peritectic decomposition don't do so well in the SPEX. They can be contaminated by the harden steel vial, and.
