Crusher Reduction Ratio - Mineral Processing Metallurgy

Jan 12, 2016  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

The chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangement of the mantle and the cone at the discharge end in the cone crusher. This is illustrated in Figure 5.2. Reduction ratios in the following ranges are common for cone crushers: 6:1 - 8:1 for secondaries 4:1 - 6:1 for tertiary and quaternary crushing.

Cone Crusher - an overview ScienceDirect Topics

The operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact [5]. The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°. The Gyradisc crushers have head diameters from ...

What affects cone crusher performance? — SRP

Any fluctuation in pressure means that the optimal force will not be delivered consistently so, of course, crusher performance declines. These are the two main causes of sub-optimal crushing performance, but losses in the reduction ratio can also be caused by selecting the wrong mantle or by having a poor chamber profile or design.
