Reduction Ratio Of Roll Crusher Calculation. We know from our examination of the crushing characteristics of these types that for equal reduction ratios the volumereductionratio in the standard gyratory is considerably higher than it is in the fine reduction crusher therefore if minimum production of fines is desirable it is logical that the heavy end of the 71 reduction should be

Roll Crusher Reduction Ratio- EXODUS Mining machine . Roll Crusher An Overview Sciencedirect Topics . The disadvantage of roll crushers is that in order for reasonable reduction ratios to be achieved very large rolls are required in relation to the size of the feed particles they therefore have the highest capital cost of all crushers for a given throughput and reduction ratio

Crushers : Smooth Roll Crushers The maximum size of the product is 2d. These operates most effectively when set to give a reduction ratio of 3 or 4 or 1. That is the max diameter of the particle is 1/3rd or 1/4th of that feed. The forces exerted by these rolls are very great from 8700 – 70000 N/cm.

The Roll Crusher usually saves head-room and weight, compact in structure and economical in first cost. lt is capable of large output AT SMALL RATIOS OF REDUCTION. For these reasons, the roll crusher lends itself to portable use or for fine crushing where ratio of reduction does not exceed 3 to 1.

Disadvantages of Roll Crushers: a) Reduction ratio is smaller than the other crushers. b) Very large rolls are required to crush small piece of ores, i.e. Capital investment is high. 4 Figure 2. Roll crusher diagram Theoretical Capacity of Roll crusher = (0.0034 * N * D * W * S * ρ) tons/hr

The rule of thumb for the Double Roll Crusher's ratio of reduction is 4:1. The simplified design gives these units excellent reliability and requires very little maintenance. The crushers are designed with built-in tramp relief that allows for the passing of uncrushable objects while remaining in continuous operation and returning to the

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. This reflects the fact that considerable

Triple Roll Crushers allow producers to accomplish two stages of reduction in a single crusher. Multiple duty classes are designed for use in coal, salt, coke, glass, trona, and other mineral processing applications. Triple Roll Crushers are capable of achieving a 6:1 reduction ratio in the primary crushing stage and a 4:1 reduction
