Jan 01, 2016 According to Bond, the average mass losses for wet and dry mills are (7.18) Wet Ball Mill kg / kWh = 0.16 (A i − 0.015) 0.33 (7.19) Dry Ball Mill kg / kWh = 0.023 A i 0.5 where A i = abrasion index. Rowland and Kjos used a constant of 0.175 in Equation instead of 0.16. The abrasion index of selected minerals is given in the Appendix (Table A-2).
