Choosing the Right Rock Crushing Equipment
The moving jaw exerts a compressive force against the stone in the chamber causing it to fracture and reduce. The rock remains in the jaws until is small enough to move down the chamber to the opening at the bottom. Jaw crushers can work on a range of stone from the softer ones like limestone to harder basalt or granite. Cone …

What Is a Jaw Crusher? Here's How It Works
Jaw crushers typically use the principles of compression and friction to break materials down. They're extremely powerful equipment that should be used with the utmost care. Jaw crushers are so powerful that they've earned the moniker "rock breakers" because of their brute force. All jaw crushers will have one fixed jaw and a moving one.
