Table of ContentsData on Ball ChargesBall Mill Ball Wear ProjectionRecapitulation of Ball Wear FormulasPractical Application of Theoretical Conclusions In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the，CALCULATION OF WEAR RATE - Grinding Media,A common used equation to compute the wear rate is (Archard,1953). V i =k i F s. where F is the normal load, s the sliding distance, V i the wear volume and k i the specific wear rate coefficient. Index i identifies the surface considered. The k-value is given in m 3 /Nm or m 2 /N, sometimes in mm 3 /Nm.Evaluation of grinding media wear-rate by a combined，,15-03-2015· Wear-rates of different grinding media are determined by two commonly used methods of self-wear in water and grinding with mineral slurry. After the analysis of all results, we design an improved testing method on wear-rate, which combines the fast process of defects formation when grinding with mineral slurry with the fast process of surface collapses of self-wear in water.Evaluation of grinding media wear-rate by a combined，,Media wear rates are not repeatable neither only by self-grinding in water nor only by grinding with mineral slurry. • New proposed wear-test method combines advantages of the above two commonly used methods. • Repeatable results on wear rates can be obtained by the combined grinding method.Modeling and prediction of wear rate of grinding media in，,Modeling and prediction of wear rate of grinding media in mineral， Speed(rpm) Grinding time(min) Wearrate(mpy) 1 8 35 720 12 70 10 462.11 2 10 45 360 12 80 10 351.45， 4.1 Predicting the wear rate of steel balls by single and multiple kernel SVM regression analysis
