As the inner cone rotates, it crushes the material against the outer shell, reducing it to smaller sizes. Gyratory crushers are unique in several ways. They can handle much harder, abrasive material and crush larger quantities faster than other crushers. They're also preferred for their ability to produce a finer, more uniform product.
