  • Ball mil design calculation? Answers

    Mar 31, 20080183;32;Best Answer 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.
