Crusher Reduction Ratio - Mineral Processing & Metallurgy
Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

Introduction to Rock Crushers - ELRUS Aggregate Systems
Sep 19, 2012 · 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.
TECHNICAL NOTES 5 CRUSHERS
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 primary operating variable available on a crusher is the set and on jaw and gyratory the open- side set (OSS) is specified.
