Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.

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

What is a crusher? A crusher is a machine that is designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size of materials, or change the form of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials so that pieces of different composition can be easy for next step separation.
