    As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles present between each rod, while no fine particles receive impact and are ground. Therefore, the Rod Mill causes no excessive grinding, enabling you to produce products of relatively sharp
