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.

Compressive crushers such as jaw, gyratory and cone crushers are known to be inefficient machines with the no-load power ranging from 30 to 50% of their rated power [18], [19]. Hence, one way to improve the efficiency of these machines is through their operation efficiency by reducing their energy consumption and cost during their operation.
