Crushers are machines which use a metal surface to break or compress materials mining operations use crushers, commonly classified by the degree to which they fragment the starting material with primary and secondary crushers handling coarse materials and tertiary and quaternary crushers reducing ore particles to finer gradations. There isn't a tremendous variation in jaw crushers, the primary differences is in their size. This paper focuses on review of a work carried out by researchers in the field of kinematic & dynamic analysis of the jaw crusher attachment. Kinematic & Dynamic analysis is helpful for understanding and improving the design quality of jaw crusher. There are many researcher work done by researcher in the same field but still there is a scope to develop Kinematic & dynamic analysis to jaw crusher attachment.Some units have hydraulic relief systems that can allow non-crushable material to go through the jaw crusher without snapping the toggle plate. These aren't terribly popular though, as pit operators seem to prefer simplicity over the rare chance of breaking a toggle plate.
