Working principle

When the 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 close to the bowl liner and far away from the bowl liner from time to time. The raw materials are pressed, impacted and finally crushed in the crushing cavity.
