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).

The working principle of hammer crusher. Hammer crusher mainly breaks materials by the impact of hammers. The material entered into the working area of the crusher is crushed by high-speed hammers. The crushed material obtains kinetic energy from the hammers, and then it impacts on the crushing plate and grate screen at high …
