Purpose – This paper aims to obtain equations that can be used to describe the motion of any given point in the swing jaw of a single toggle jaw crusher. Design/methodology/approach – The swing jaw drive mechanism of a single toggle jaw crusher is modelled as a planar crank and rocker mechanism with the swing jaw as the coupler link. …
contact force model, and the friction force model is introduced. In Section 3, the dynamic model of the crusher working mechanism with clearance is established by the Lagrange multiplier method (LMD).
1.2 The jaw crusher. Crushing is the first stage of size reduction of mined rocks. Primary crushers are heavy-duty machines, used to reduce the run-of-mine (ROM) ore down to a size suitable for easy handling. A line diagram of a double toggle jaw crusher and its main components is shown in figure 2. The jaws are set at an angle to each other.
