During the crushing process, the worn condition of the sealing ring between the shaft frame and the mainframe should be checked.After a long term of use, this part of cone crusher may be worn and the original flexibility of the sealing ring would be reduced.

When the spring cone crusher is working, the motor drives the eccentric bearing bushing via spring coupling, transmission shaft and a couple of cone gear wheel.The crushing cone axis is forced to swing by the eccentric bearing bushing, which makes the mantle sometimes close to the bowl liner,stone crushing plant and some times far away from the bowl liner.The raw materials are pressed, impacted and finally crushed in the crushing chamber.
