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. The basic principle for rod

Ball-Nose End Mills. Ball-nose end mills have a dome-shaped tip. These excel at high-detail contours like relief artwork or mold and die making, but have what is known as “scalloping.” Since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple fishtail to smooth

SAG mill vs Ball mill Crushing ratio. The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach
