Definition of reduction ratio. In crushing, the ratio of the size of the largest feed particle to the smallest distance between the roll faces. As used frequently in the field, it is the ratio of the smallest aperture passing all of the feed to that passing all of the product.
In any crushing operation, the raw material flow rate and the reduction ratio ratio of feed size to product size have obvious influences on the wear of crushing equipment. However, the hardness and fracture toughness of the rocks being crushed are unavoidable parameters in allowing for the wear of crushing

Unless very large diameter rolls are used, the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 41 are rare, a flowsheet may require coarse crushing rolls to be followed by fine rolls.
A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 61 reduction ratio. Thus, with a 34 closed side setting, the maximum feed would be 6 x 34 or 4.5 inches. Reduction ratios of 81 may be possible in certain coarse crushing

assumed that the energy required is equal to the reduction ratio based on the ratio of the volume before to the volume after crushing. Thus, the energy required is directly proportional to the size reduction, e.g. the same amount of energy is required to go from 2 to 1 cm as from 1 to 0.5 cm. i f K ln x x E k 11.4
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.

The difference between a conventional impactor and a VSI of the Barmac type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a Barmac VSI, the material undergoes an intense rock-on-rock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.
