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).

You might need to have a surgical procedure called shock wave lithotripsy that uses sound waves to break the stone up into smaller pieces, making it easier to pass. Surgeons can also use a special camera called ureteroscope (a narrow tube with a camera at the end) to get to the stone in the ureter or kidney and break it up using laser.

Crushed stone is obtained quite simply by crushing various rocks, such as gravel, boulders, and various simultaneously mined interfering rocks or waste from non-conditioning. Crushers of different designs are used to produce crushed stone: roller, cone, cheek crushers [3-6]. Roll plants crush stone as a result of its crushing.
