© Copyright R P King 2000 TECHNICAL NOTES 5 CRUSHERS

5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size. The gape determines the maximum size of material that.
