Abstract: In this paper, the traveling characteristic value of moving jaw of jaw crusher is studied by optimization experiment. The traveling characteristic value can reflect the relationship between capacity and energy consumption of jaw crusher. When it is around 2.5, the capacity of jaw crusher is high and the energy consumption is low.

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.
