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.
