Analysis of Conical Deformation of Cone Crusher

Cone crusher since the emergence of the market quickly by the favor. In the course of its work, due to some reasons, the crusher of the dynamic cone will appear the phenomenon of instability, if not dealt with in time, will have a great impact on the production of crusher.


Cone crusher

Cone crusher machine in the broken ore, broken cone for regular movement. Since the center of mass of the crushing cone and the eccentric sleeve are not on the center line of rotation, the inertia force and the moment of inertia of the fixed suspension point are inevitably generated during the operation. They act on the rack, showing a periodic dynamic load, causing the vibration of the frame and the deflection of the eccentric sleeve. In view of this phenomenon, although the researchers in the design with the crusher to take a balance, to eliminate this harmful effects, but in actual production often due to manufacturing, installation, lubrication and other reasons, resulting in broken motor cone instability, thus affecting The normal operation of the crusher.


During the operation of the crusher, the stability of the movable cone is manifested in two aspects: one is that the movable cone is overturned and the spindle is caught in the eccentric sleeve, and the movable cone is rotated at zero relative to the rotation speed and along with the eccentric sleeve, Turn very fast, this dynamic cone instability phenomenon known as the crusher "flying cone" phenomenon. And the second is the dynamic cone tipping but not serious, moving cone can still be relative rotation, but its absolute rotation speed exceeds the operating rules specified by the speed range, which is also known as dynamic cone instability phenomenon. In combination with these two aspects, we can not guarantee that the dynamic cone in the limited speed range of stable operation of the phenomenon, known as the "instability."


Due to the instability of the dynamic cone will make a serious accident crusher, and even the spindle fracture, broken, tapered bushing cracking and other failures, it must be timely to find the reasons for the instability of the dynamic cone, and timely treatment, the crusher back to normal jobs.
