Energy consumption of a laboratory jaw crusher during normal …
Cumulative crushing energy is plotted in Fig. 7 for different concrete strengths. It can be seen that the energy consumed for crushing the specimens (on the aperture size 25 mm), depends on the concrete compressive strength. Higher strength, 70 MPa and beyond, require higher energy for crushing compared to normal strength, i.e. below 70 MPa.
