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.
