Cause of Instability of Cone Crusher Cone

Cone crusher in the course of the operation, because the dynamic cone failure will cause serious accidents crusher, or even the spindle fracture, break, cone bushing cracking and other faults, it must promptly find out the reasons for dynamic cone instability, and Timely processing, the crusher to resume normal work.


Cone crusher crushing the ore, broken cone for regular movement. As the crushing cone and eccentric sleeve center of mass are not in its rotation center line, so in the course of operation will produce inertia force and fixed moment of inertia of the suspension point. They act on the frame as a periodic dynamic load, causing vibration of the frame and skewing 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 effect, but in actual production is often due to manufacturing, installation, lubrication and other reasons, resulting in crushing maneuver cone instability, thus affecting Crusher the normal operation.

During the operation of the crusher, the stability of the dynamic cone in two aspects: the first is the moving cone overturned, the spindle stuck in the eccentric sleeve, then move the cone relative rotation speed is equal to zero and follow the eccentric sleeve together with the rotation , Turn very fast, this dynamic cone instability phenomenon known as the crusher "flying cone" phenomenon. The second is the dynamic cone tipping but not serious, the dynamic cone can still make relative rotation, but the absolute speed of rotation than the relative operating procedures specified speed range, which is also known as the dynamic cone instability phenomenon. These two aspects can be seen, all can not guarantee that the dynamic cone in the limited speed range of stable operation of the phenomenon, known as the "instability."
