What is a Jaw Crusher? – MEKA Crushing Equipment
This is the third stage of crushing. The size, which is around 50–80 mm, of the ore or rock from the secondary crushing process is reduced to between 5 and 12 mm. We call the machine that performs the CRUSHING process a CRUSHING MACHINE or CRUSHER. MEKA Size Reduction Machines WHAT IS A JAW CRUSHER? / JAW CRUSHER

2019-5-13 Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.

Jaw Crusher - an overview ScienceDirect Topics
The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate.
