Cement millWikipedia
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
