Solution for Breakage of Spindle and Bush of Cone Crusher

The cone crusher is favored by a lot of mining enterprises because it has a lot of advantages. However, the economy in this year is not booming, so the mining machinery industry suffered a landslide. With the economic policy, the domestic economy begins to recovery with stability. Especially some of the large projects promote the development of the cone crusher. In this article, the experts of Henan Hongxing Mining Machinery will mainly analyze the solutions for breakage of the spindle and bush of the cone crusher.
When the cone crusher works normally, the crushing cone does the regular movement. The center line of the crushing cone and the eccentric sleeve are not on the rotating centerline. Therefore, in the operation process, the inertia force and the inertia moment of force for the fixed suspension point is bound to be produced. They are acting on the rack of the cone crusher. Although balanced measures have been taken for the cone crusher, the errors in terms of the manufacturing and installation may lead to the frequent contact between the lower end of the spindle of the crusher and the eccentric sleeve, which may cause breakage of the spindle. The lower end of the cone bushing may be broken. The breakage of the spindle may have a great impact on the service life of the crusher.
The experts have put forward the following ways to avoid the breakage of the spindle. On the belt conveyor before the cone crusher, install a metal detector and the suspension magnets to remove the metal objects in the ores to prevent the metal objects from falling into the crushing cavity. During the installation process, the heating temperature of the cone body and the cooling speed after the assembly should be controlled strictly to improve the strength of the spindle and reduce the concentration of the stress. Before the assembly, you should carefully check the hole and the spindle to prevent the unnecessary inner stress. The structure of the spindle should also be improved.
In terms of the cone sleeve, you should make the two thirds of the contact area of the sphere bearing on the outer ring when the sphere bearing is replaced.
