How do you calculate jaw crusher capacity ...

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.

Crusher Reduction Ratio - Mineral Processing & Metallurgy

2016-1-12 · 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.

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.
