Cone crushers have gained such wide acceptance that they may be regarded as standard in the intermediate-range size-reducing machines. A schematic diagram of a cone crusher is shown in Fig. 4.6 A.The drive is similar to that of a gyratory crusher. The inner cone or 'crushing head' is supported by the tapered concentric spindle, which is rotated by the …Web

Therefore, these additional compact copper ore grinding machine may be given into mill for example ball mill for grinding.

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:Web

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.Web
