Crusher Reduction Ratio - 911 Metallurgist

12-01-2016· 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.

What affects cone crusher performance? — SRP

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. Surprisingly, selecting the wrong alloy has no effect when it comes to the reduction ratio (although this will affect the life of wearable parts in your crusher).

TECHNICAL NOTES 5 CRUSHERS - Mineral Tech

High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers. 5.1.3 Crushing mechanisms and product size distributions.

CHAPTER 11 SIZE REDUCTION - NZIFST

Kick assumed that the energy required to reduce a material in size was directly proportional to the size reduction ratio dL/L. This implies that n in eqn. (11.1) is equal to -1. If K = K K f c where K K is called Kick's constant and f c is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E ...
