What is the Eccentric Assembly of the Cone Crusher?

The eccentric assembly is mounted on the main shaft. The eccentric typically features a precision-machined internal surface to ensure a close fit with the eccentric bushing, reducing friction and extending component life. It houses a counterweight assembly on the outside, a large gear on the bottom, and an upper thrust bearing. It is one of the key components that enables eccentric motion in the equipment.

In a crusher, the eccentric assembly is a crucial component of the drive system. It rotates the eccentric through a transmission device (such as a motor), which in turn drives the crushing cone or grinding disc into a oscillating motion. This motion continuously impacts and compresses the material within the crushing chamber, ultimately achieving a crushing or grinding effect.
