dynamic modeling of a rock crushing process

Modelling the size of the crushed zone around a blasthole ...

As the process of crushing is dynamic, a crushing zone model should include dynamic rock material properties. However, many of these dynamic properties cannot be directly measured and are not readily available, resulting in the use of assumed multipliers.

Impact Crusher Working Principle - 911metallurgist.com

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).
