Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

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.
