The reduction ratio of a jaw crusher is a measure of how much the size of the material being crushed is reduced. It is calculated by dividing the input feed size by the output product size. For example, if the material entering the jaw crusher is 1000mm in size and the material exiting is 100mm, the reduction ratio would be 10:1. Typically, jaw crushers have a reduction ratio ranging from 4:1 to 6:1, though they can be adjusted to achieve higher ratios for specific purposes. The exact ratio depends on the design and operational parameters of the machine.
