The main advantage of tertiary crushing is that it produces a high-quality, fine-grained end product that is suitable for use in various applications. Tertiary crushers also offer improved efficiency over secondary crushers by reducing the number of crushing stages required to produce the final product.
Abstract. In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.

Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. 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 TTT-Plot for jaw crusher unit concaves downward which reveals increased rate of failures. This is also supported by the shape parameter value 1.17 of Weibull distributions. It also indicates that the jaw crusher as a whole unit is entering the wear-out phase. Table 4 Data for TTT-plot of jaw crusher unit.
