Experimental Study on Cement Clinker Particles under Impact Force

Abstract:

In order to further study the impact crushing mechanism of cement clinker, the impact experiment has been carried out at different impact angles. Impact crushing curves, acoustic emission signal and peak impact force and impact fracture morphology have been systematically studied. It is shown that each impact crushing curve includes an inertia peak and an actual impact peak. AE signal directly reflects the crack initiation and propagation during the process of impact experiment. With the increase of impact angle, the average value of peak impact force decreases. The peak impact force value reaches the minimum at 75 °. The experiment results will offer a successful alternative to the low – energy grinding of cement clinker.
