and rod mills are well suited to handle finer feed and to control the smaller size of the product. Ball mill Tube type can grind materials to a fineness of minus 200mesh and is used as a secondary grinding mill after the Ball Mill Conical type or Ball mill Grate type.SAG mill throughput as a function of grate open area As shown in Figure 2 the grate open area has a strong effect on Sossego SAG mill throughput. The nominal capacity of the circuit should be achieved with a combination of 13.5% ball charge and 10.8% open area with 3 and 3.5 inch apertures.The 24' x 39.5' Ball Mill The Copper Mountain ball mills are 7315 mm [24 feet] in diameter and 12040 mm [39.5 feet] long.
