A fundamental model of an industrial

May 01, 2017· To achieve a model using physical modelling techniques, the machine of interest, a jaw crusher in this case, has to be broken down into smaller subsystems and modelled separately, for example, breakage, dynamics or pressure, as seen in Fig. 1.For this research, the modelling approach is similar to the approach used by Evertsson (2000) when developing an analytical model for a cone crusher.

A fundamental model of an industrial

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).
