What is a Jaw Crusher? MEKA Crushing Equipment

R: Size reduction ratio. The ratio of the gape width to the near side jaw opening. This ratio may vary from 1/3 to 1/9, but is generally 1/3 for primary crushers and 1/4 for secondary crushers. θ: Nip angle. One of the most important parameters is the angle between the two jaws, which is referred to as the nip angle.Tips to maximize crushing efficiency Pit & Quarry,Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6to1. 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.
