They can also break sedimentary deposit-type rocks—limestone and similar—along natural lines, which rounds off sharp angles and weak edges. This can produce a result that is more sand-like in nature.

Gyratory Crusher
An impact crusher breaks the CDW materials by striking them with a high-speed rotating impact, which imparts a shearing force on the debris (Figure 4.4(b)). Upon reaching the rotor, the debris is caught by steel teeth or hard blades attached to the rotor. These hurl the materials against the breaker plate, smashing them into smaller particle sizes. Impact crushers provide better grain-size
