Gyratory crushers are a type of rock crusher that operate using a spinning motion. The rock is crushed between two cones and forced between crushers in a gyrating motion. Cone crushers are more expensive than jaw crushers, but they can produce a higher quality product because they use a crushing motion combined with a pressing action.
