maximum reduction ratio for primary crusher

Crusher Reduction Ratio - Mineral Processing Metallurgy

2016-1-12  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.

TECHNICAL NOTES 5 CRUSHERS - mineraltech

2009-7-30  Maximum size that can be accepted into 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 primary operating variable available on a

2019-5-13  The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent. The finer the closed-side setting, the greater the proportion of fines produced. The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees.

Gyratory and Cone Crusher - ScienceDirect

2016-1-1  The product size from a primary crusher is limited by the possible reduction ratio, which normally is around 10:1. The feed size to a primary crusher from the mines could be 1–1.5 m; thus, the maximum product size possible is 10–15 cm which is normally too large for down stream processing for mineral liberation.

Cone Crushers McLanahan

A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8:1 may be possible in certain coarse crushing applications.
