Perhaps many people do not know what the impact of insufficient spring pressure cone crusher, cone crusher leasing manufacturer reminds you, once this situation occurs, it is likely to lead to spindle broken! The following edition will give you a detailed popularization!
Overload operation: Due to insufficient spring pressure of cone crusher, the upper support sleeve of cone crusher often jumps when overload occurs, resulting in coarse product size. Therefore, operators often take the method of re-compressing the safety spring to increase the breaking force, thereby increasing the force on the spindle, resulting in the main bearing being subjected to excessive force;
Frequent iron-crossing and iron-jamming: In order to obtain qualified product size, the crushing workshop often reduces the tapping mouth, resulting in an increase in the number of iron-crossing or iron-jamming in the crushing chamber, resulting in a certain value of bending stress in the dangerous section of the spindle, leading to a broken spindle of the conical crusher.
The interference of the static pressing part of the spindle is reduced, and the fit interference between the spindle and the conical body is reduced. In order to ensure that the spindle and body do not loosen in the process of operation, a certain interference is required. The bigger the interference is, the firmer the shaft will be, but the stress concentration will also increase and the fatigue strength of the spindle will decrease more seriously.
Increase the transition circle angle between the spindle mating part and the cone to reduce the stress concentration factor; Increase the load-reducing groove to reduce the pressure matching; Make a circle of load-reducing groove at the lower edge of the body of the static pressing part between the spindle and the broken cone body; Improve the rounded shape of the broken part of the spindle and roll the static pressing part of the spindle. Press processing, increase its surface finish and surface hardness.
