For example, the comminution process of cement clinker followed the firstorder grinding kinetics with the balls and rod media. Meanwhile, the grinding rate of the rod mill was higher than the ball mill [22]. The equivalent granule size declined while its specific surface area increased gradually with grinding time [23].
