The reduction ratio is the ratio of feed size to product size, often with reference to the 80% passing size, that is, reduction ratio=F 80 /P 80. If the ore tends to be slippery and tough, the tertiary crushing stage may be substituted by coarse grinding. On the other hand, more than three size-reduction stages may be required if the ore is extra-hard, or in special cases where it is important

When there are more crushed materials in the raw ore, the use of pre-screening can reduce the workload of the crusher, and the use of a smaller model can increase the system’s yield and reduce the over-crushing of the product. The overall power consumption is reduced, and the metal consumption is reduced. As the pre-screening adds a link and the complexity of production increases, it is

Size Reduction is mainly done through crushers and mills. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on the "run-of-mine" ore. The grinding process which is normally carried out after crushing, may be conducted on dry or slurried material. 2.0 The size reduction process:
