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).

The raw coal is then fed into the pulverizer where it is ground into fine coal particles. What are the Advantages of Pulverized Coal? Pulverized coal produces a larger amount of heat than traditional coal. This leads to more fuel-efficient and easier-to-burn low-grade fuel sources. This type of coal fineness increases the surface area for burning.
