In the working process of the cone crusher, the motor drives the eccentric bushing to rotate through the transmission device, and the dynamic cone rotates and swings under the force of the eccentric bushing, and the section where the dynamic cone is close to the static cone becomes the crushing cavity, and the material is crushed by the extrusion and impact of the dynamic cone and the static cone for many times. When the moving cone leaves the section, the material that has been crushed to the required size will fall under its own gravity and be discharged from the bottom of the cone.
Operation Mechanism
As shown in Figure 2, the crushing process is completed between the fixed fixed cone and the rotary movement of the moving cone. When the cone crusher is working, the horizontal axis of the crusher is driven by the motor through the triangular belt and pulley, and the horizontal axis drives the eccentric sleeve to rotate through the large and small gears, and the cone axis of the crusher does the rotary oscillation movement under the action of the eccentric sleeve to make the surface of the crushing wall close to the surface of the fixed cone at times and far away from the surface of the fixed cone at other times, so that the materials are continuously crushed by the extrusion, fracture and impact in the crushing cavity. The crushed material is discharged from the discharge opening at the lower part of the crusher under the action of self-weight. The upper chamber of the cone crusher’s motorized cone is supported on the spherical shaft tile at the upper end of the fixed main shaft, and its lower chamber is set on the outside of the eccentric shaft sleeve, and its movement is directly driven by the eccentric shaft sleeve. When the eccentric bushing rotates around the main shaft, the moving cone not only rotates with the eccentric bushing around the center line of the machine, but also rotates around its own axis, and the moving cone is rotating around its spherical support center for spatial swing motion. The axis of the moving cone and the spindle center line intersect at a fixed point, that is, the center of the spherical surface, and its angle is the angle of entry. When the crusher is running, the axis of the moving cone makes conical movement relative to the centerline of the machine, and the top of the cone is the spherical support center, which is always stationary during the movement of the moving cone. Therefore, the motion of the moving cone can be regarded as the rotation of the rigid body around the fixed point, i.e. the motion of the moving cone is composed of two kinds of rotary motion: the in-motion motion or implicated motion (the moving cone rotates around the centerline of the machine) and the rotary motion or relative motion (the moving cone rotates around its own axis).
Cone crusher in no-load operation, cone rotation is by the spherical bearing to the cone of the friction torque and eccentric bushing to the cone of the friction of the numerical value of the decision, which torque is large, then the cone that is in accordance with the direction of this torque to rotate. Under normal circumstances, the cone rotates in the direction of the eccentric shaft sleeve, and the rotation speed is determined by the difference between the two moments. The cone crusher is equipped with spherical bearings and the lower bushing of the cone to control the rotation of the cone. Under loaded operation, the friction moment of the stone material on the cone face of the cone far exceeds the friction moment of the eccentric bushing on the cone.
