Ball Mills Mineral Processing & Metallurgy

2017-2-13  Difference Between Ball Mill and Rod Mill Rod Mills. The principal field of rod mill usage is the preparation of products in the 5 mm—0.4 mm (4 mesh to 35 mesh) range. It may sometimes be recommended also for finer grinding. Within these limits a rod mill is usually superior to and more efficient than a ball mill.
