Crushing. To reduce run-of-mine to mill feed requires reduction in a series of stages. The physical size and power requirements of a crusher capable of reducing hard rock vary depending on the application. Extended experience in most crushing plants show that a minus 19MM (¾") rod mill feed can be and is being produced in three stages of ...

Additionally, gyratory crushers have a higher crushing ratio (meaning that they can crush large material into smaller pieces), a larger feed opening, and a more consistent product size and shape compared to cone crushers. However, cone crushers have a more efficient crushing action for smaller materials but can produce more fines.
