However, loads in a mill are not clearly and precisely defined. Of course, there are rules to calculate the maximum stress in rolls caused by design limits for maximum separation force, torque, Hertzian pressure etc, but these criteria are valid only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone. Besides “normal

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs
