Spherical balls or cylindrical rods are mostly used as the grinding media. These media cascade within a mill and impinge on the ore, thus providing a crushing action. As the balls and rods tumble within tubular mills, they provide a grinding action and forces of attrition, all of which result in further reduction of the size of the rock particles.

Many commercial hard rock mines will do 80 or 100 mesh, but screen between steps, so the ore is not over crushed. Once you reach the desired size, you don't want to keep crushing. Even with leaching - you don't want to over crush - you can produce an ore that fluids won't flow through - think of trying to flush water through a bed of solid clay.
