Upper Head wear bush

In the working process of cone crusher, the motor drives the eccentric sleeve to rotate through the transmission device, and the moving cone swings under the force of the eccentric sleeve. The section of the moving cone near the static cone becomes the crushing chamber, and the material is crushed by the multiple extrusion and impact of the moving cone and the static cone. When the moving cone leaves this section, the material that has broken to the required size falls under its own gravity and is discharged from the bottom of the cone. In order to reduce the wear between the eccentric bushing and the shaft, bushing is usually set between them. However, the existing bushing is only a cylindrical bushing. Because of the lack of lubricant between bushing and eccentric bushing and shaft, it is easy to wear and damage bushing. Its frequent replacement greatly affects the production efficiency.ronze.
