A jaw crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. This paper focuses on review of a work carried out by researchers in the field of Kinematic and Dynamic analysis of the jaw crusher attachment. The basic problem in the study Predicts the ...

As shown in Fig. 2 a, a large jaw crusher was used to reduce ore from the mine to an 80% passing size (P80) of 100–150 mm. A cone crusher was then used in closed circuit with a screen producing a 20–30 mm product which could then be fed with some added water into a tumbling mill filled with heavy steel rods (called a rod mill).
