Introduction to Kinematic Analysis about Impact Crusher

The centerline and the centerline of the moving cone of the impact crusher intersect at a fixed point and they form an angle. Due to the characteristics of the structure, the movement of the moving cone is bounded by the eccentric sleeve and it has to do cycle exercise. In the mechanics, the materials do the space rotation around the fixed point. From the production practice, we know that the moving cone does the clockwise or counterclockwise cranking motion around the center line of the machine with the eccentric hole. In addition, it also does the rotation in the turning direction around the instantaneous axis with the eccentric sleeve.
When the impact crusher crushes the materials, the movable cone does the clockwise or counterclockwise cranking motion around the center line of the machine with the eccentric hole of the eccentric sleeve. At the same time, it also rolls along the materials layer of the crushing cavity. Why the state of this movement will appear? The excerpts of Henan Hongxing Mining Machinery will analyze the reasons for you in the following paragraph.
For the kinematics analysis of the impact breaker, we can know that both load operation and the no-load operation are small. Therefore, in the calculation of kinetic analysis, the operation can be considered as 0. The crushing cone of the impact crusher and the center of mass of the eccentric sleeve are not on their rotation center line. As a result, the inertial force and the fixed point are inevitably produced in the operation. The fixed point and the inertial force may increase angle. Since the angle is limited by the structure of the eccentric sleeve, it will not be changed. Therefore, the machine will produce a kind of harmful vibration if the rack sleeve and the spherical bearing shell produces a kind of action force. The eccentric sleeve is prone to be deviated, which will affect the normal operation of the machine. In order to eliminate or reduce the harmful vibration caused by this inertia force and moment of inertia and ensure the normal operation of the machine, the key is to calculate out the size of the inertial force and moment of the inertia force of the eccentric sleeve of the crushing cone.
