Roll Crusher
As mentioned earlier, the diameter to be adopted for the rolls is dependent upon the feed size and the nature of the material to be crushed. Since the reduction ratio for one pass of the material through a roll crusher is about 5–1, a higher reduction ratio may be obtained by putting the material through two crushers operating in series.
Types of Crushers Explained: Everything You Need to Know
Limited reduction ratio, lower capacity compared to gyratory crushers: Cone Crusher: ... Unlike jaw crushers, gyratory crushers generally have higher reduction ratios. Consequently, they can produce smaller output sizes in a single pass. Moreover, they have a higher production capacity and can do more material per hour. ...
Gyratory Crusher
The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.
Assessing the energy efficiency of a jaw crusher
For a jaw crusher the reduction ratio (R) is defined with gape (G) as: (A.1) R = G L min [−] Therefore the close opening set (L min) for a jaw crusher can be written as: (A.1) L min = G R [m] Rose and English [4] determine the size for which 80% of the feed passed, by considering a large data set relating the maximum particle size to the ...

Crusher Reduction Ratio
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 ...
Jaw Crusher Diagram: Simplified Guide
In a crusher's design, attention to the reduction ratio is critical. This ratio reflects the degree to which the material is reduced in size from the feed to the product. A high reduction ratio indicates a powerful crushing capacity, such as reducing 150-centimeter-wide iron ore to a 30-centimeter-wide material.

McLanahan | Triple Roll Crushers
The ratio of reduction is the ratio of the feed size to the desired product size. For example, if the feed size is 12" and the desired product size is 3", then the ratio of reduction is 4:1. With Triple Roll Crushers, you have a 6:1 ratio on the top stage followed by a 4:1 ratio on the bottom stage.
P&Q University Lesson 7: Crushing & Secondary Breaking
