Impact of Rock Hardness on Fragmentation by Hydraulic Hammer …
Accordingly, the hammer will operate longer and use up more energy with the rocks of low hardness. Compared to the hydraulic hammer it has been found ( Figure 11) that hardness has a minor impact on the specific energy of crushing in jaw crusher, which is proved by a very low value of the correlation factor (R 2 = 0,0033).

Impact Crusher Working Principle
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).
