There are several main types of copper sleeve within the crusher:

Eccentric bushing copper sleeve:

Location and connection: located in the eccentric device part of the crusher, connecting the eccentric shaft and other related parts.

Role: To enable the eccentric shaft to drive the moving cone to carry out eccentric movement, to realize the extrusion of materials, crushing and other operations. It is one of the key parts of the crusher as it needs to withstand large friction force, impact force and reaction force from the crushed material when working.

Copper sleeve of dynamic cone:

Position and connection: installed on the moving cone, wrapped around the main shaft part of the cone.

Function: Reduce the friction between the cone and the crusher frame, so that the cone can rotate freely in the crusher to ensure the normal operation of the crusher. During the working process, the copper sleeve of the moving cone is constantly impacted and worn by materials, so it needs to have high wear resistance and strength.

Horizontal axis copper sleeve:

Position and connection: Located on the horizontal axis of the crusher, set on the outside of the horizontal axis.

Role: It plays the role of supporting and lubricating the horizontal shaft, and bears the weight of the horizontal shaft and the friction generated when the shaft is rotating. The good working condition of the horizontal shaft bushing is very important to ensure the overall stability and efficiency of the crusher.

Main shaft sleeve(also called conical copper sleeve):

Location and connection: Installed on the outside of the main shaft due to its tapered appearance. It is applicable to the main shaft of spring-type and Simmons-type cone crusher.

Role: It mainly plays the role of protecting the main shaft, avoiding the wear and tear caused by the direct contact of the main shaft with other parts, and at the same time, it can also reduce the friction and vibration to a certain extent, so as to ensure the normal operation of the main shaft.

Bowl type copper sleeve:

Location and connection: Generally installed in the bowl bearing part of the cone crusher.

Role: It cooperates with the moving cone and the frame and other parts, bears the load transmitted by the moving cone, and plays the role of guiding and supporting during the movement of the moving cone, so as to make the movement of the moving cone more stable and accurate. The wear and tear of the bowl type bronze sleeve will directly affect the working performance and crushing effect of the crusher.
