  • Gyratory Crusher an overview ScienceDirect Topics

    Similar to jaw crushers, the mechanism of size reduction in gyratory crushers is primarily by the compressive action of two pieces of steel against the rock As the distance between the two plates decreases continuous size reduction takes place Gyratory crushers tolerate a variety of shapes of feed particles, including slabby rock, which are not readily accepted in jaw crushers
