rail cars and make 4 to 5 trips per day. Crushers are the first stage of ore processing. Depending upon the application, power can range from 180 kW (240 HP) to 1200 kW (1600 HP). Rocks as large as 50 cm in diameter are reduced to 15 cm fragments [11, 13] which are then reduced to fine particles in SAG (Semi-Autogenous Grinding) or Ball mills.

program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion rate was calculated by Equations 4, 5 and 6. Total mill feed per week = 720*24*7*0.95= 114912 tons (4) Total ball charge per week = 7*106 g (5)
