In recent years, various shapes of grinding media including rods, pebbles, and cylinders have been used as an alternative to balls. Cylinders have received particular attention because they have a greater surface area and higher bulk density than balls of similar mass and size [9]. The grinding of quartz has been found to obey first-order ...Web
