Attrition: Rotary Ball Mill. A hollow steel cylinder containing tungsten carbide (WC), corundum (αAl. 2 O 3) or ZrO 2. balls and a solid precursor rotates about its central axis. Particle size is reduced by brittle fracturing resulting from ballball and ballwall collisions. Milling takes place in an inert gas atmosphere to reduce contamination.

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 highchromium smaller grades are occasionally cylindrical ("pebs ...
