Numerical analysis for force distribution along the swing jaw plate of a single toggle jaw crusher

Abstract

Purpose The purpose of this research work is helpful for recognizing the crushing characteristics of a single toggle jaw crusher during its operation. It is useful for designing a new prototype of this kind of machine with optimal dimensions of the jaw crusher frame and the crushing chamber. Design/methodology/approach The efficiency of the jaw crusher primarily depends on the kinematic characteristics of the swing jaw plate during the crushing process. The present research work deals with the kinematic analysis of the swing jaw plate of a single toggle jaw crusher. Findings During the analysis, the system is considered as a four-bar crank rocker mechanism. The force distribution is analyzed based on the results obtained from the motion analysis of the swing jaw plate. Originality/value The movement of the swing jaw plate is explained in detail while the machine is in operation. Kinematic analysis of the liner has been performed by considering some points along the swing jaw plate. The results obtained from the movement analysis of the swing jaw plate force distribution along the liner are analyzed. From this analysis, the chamber geometry can be optimized according to the requirement for the crushing motion of different zones in the crushing chamber.
