A gyratory crusher is a type of crushing machine used in mining and aggregate industries to break down large rocks into smaller, manageable pieces. It operates by using a conical head that moves in a circular motion, crushing the material against a stationary outer shell. This design allows for efficient size reduction and is particularly effective for hard materials. The gyratory crusher is known for its high capacity and ability to handle large volumes of material. It is commonly used in primary crushing applications, where it can process large chunks of ore or stone before they are further reduced in size by other types of crushers.
