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]. The grinding kinetics of quartz and chlorite followed the first-order breakage behavior in wet ball milling [24].
