Cone Crusher Main Shaft Fracture Reasons. Cone crusher main shaft fracture reasons can be divided into 2 aspects: main shaft reason and production reason. Main Shaft Reason. Main shaft structure design is unreasonable. For example, shrink range of main shaft and mantle fitting surface is too large, no discharge launder or transitional circular

If the interference between the main shaft and the moving cone is too large, there is no unloading groove, and the transition fillet is too small, the main shaft is prone to stress concentration, resulting in fatigue damage to the main shaft. Or the diameter of the main shaft is small, and the main shaft is more prone to break when there is "over-iron" phenomenon in the equipment.

The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501). The crushing head is carried on a short solid main shaft (515) suspended from the

An eccentric shaft rotated by a gear and pinion produces the oscillating movement of the main shaft. The eccentricity causes the cone head to oscillate between the open side setting (o.s.s.) and closed side setting (c.s.s.). In addition to c.s.s., eccentricity is one of the major factors that determine the capacity of gyratory and cone crushers
