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).

Experimental Study on Crushing Characteristic of Coal

Crushing characteristics of coal and gangue under impact load were expressed by crushing ratio and crushing probability. Experimental results showed that crushing ratios of coal and gangue decreased with an increase of particle size and impact velocity. As the impact velocity was between 5–8 m/s and the initial particle size was between 50

Impact Crushing of Particle-Particle Compounds

The liberation of aggregates is carried out by impact crushing in a large scale pneumatic cannon. Both experiments and Finite and Discrete Element simulations are adopted to study the cracking phenomena of aggregates. Also, the different aspects of crushing of particle-particle compounds at different velocities are discussed.
