Reasons for the Bending of the Eccentric Shaft of the Jaw Crusher and Its Solutions

Reasons for the bending of the eccentric shaft of the jaw crusher：

1.During the hoisting process of the main unit, a rollover occurs, causing the eccentric shaft to be stressed unilaterally and bend.

2.The hardness of the material to be crushed exceeds the specifications stated in the product instruction manual.

3.The main unit of the jaw crusher operates under overload for a long time.

4.The main unit of the jaw crusher operates under overload for a long time.

5.The heat treatment of the eccentric shaft is improper, resulting in stress concentration and causing the shaft to break within a short period.

Corresponding solutions:

1.Replace the eccentric shaft with a new one and hoist the main unit correctly.

2.Replace the eccentric shaft with a new one, and select a suitable crusher according to the compressive strength of the crushed material.

3.Replace the eccentric shaft with a new one, adjust the operation load or replace it with a suitable crusher.

4.Replace the eccentric shaft with a new one, and do not use toggle plates and toggle plate pads that do not meet the design standards.

5.Replace the eccentric shaft with a new one, and use an eccentric shaft that has passed the heat treatment inspection.
