<jats:p>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.</jats:p>
