Reduction Ratio: Ratio of Size of Feed to Size of Output. the feed material. It should be 80% to 90% of the gape and it should also be a uniform size.

In crushing, the ratio of the size of the largest feed particle to the smallest distance between the roll faces. As used frequently in the field, 

Reduction ratio generally varies between 3 to 6 or 7. Theoretical Capacity of Jaw Crusher = (0.6 * W * S) tons/hour, (W: Width", S: Set") 

Jaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 ratio. The finer the crushing, the smaller the reduction ratio. As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept.
