  • Grinding Media Wear Rate Calculation in Ball Mill

     · Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

  • Exploring ball size distribution in coal grinding mills

     · The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% ( 45% increase), power draw increase is 31%, while capacity increases by 51%. For the 50 mm balls the respective increase in power and capacity is 28% and 42%.
