    Jaw Crusher Working Principle

    May 06, 2021 Required reduction ratio; A jaw crusher size is obtained by looking at its feed opening (gape) and length. As an example, a monster 7959 of 79″ x 59″ (2m x 1.5m) will have its fixed jaws 79″ apart where the feed enters on a 59″ wide set of liner plates. The factors list below will enhance crusher capacity and performance: 1

    Using the F80 rule with the 32 x 54 Jaw Crusher, the 32” gape opening equals a 26” top sized feed, and with the 6:1 ratio of reduction, the discharge setting would be around 4”. Since the crushing of the material is not performed in one stroke of the eccentric shaft, massive weighted flywheels are attached to the eccentric shaft and

    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

    A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated
