The impact crusher uses the high-speed rotation of the rotor, leaving the material entering the rotor into the crushing chamber, thus making it collided with each other and break up. Therefore, it is necessary to analyze the material state of the rotor and the broken chamber, so as to further understand the mechanism of the crushing.
When the impact crusher rotates at high speed, the rotor accelerates the material, and the rotor is subjected to the complex dynamic load caused by the flow of material. Under the action of the dynamic load, the rotor will easily produce complex vibration and drive the vibration of the bearing box support under the rotor. The dynamic characteristics and vibration response characteristics of the two are the same. The performance of the crusher is significant, so it is necessary to analyze the vibration of impact crusher.
In crushing industry, the parameters in crushing work are complex and changeable, such as material characteristics, working characteristics, etc., so many dynamic data are difficult to observe. In order to accurately and effectively understand the relationship between the various factors in the process of breakage and their influence on the various indexes of the production process, so as to find out the solutions quickly and reasonably, to establish the broken mathematical model and to carry out the simulation analysis become the necessary methods and means. Through the animation display of the modal vibration mode of the impact crusher, the vibration process of each order mode of the rotor structure of the impact crusher is described, and the relevant conclusions are obtained through the analysis of the natural frequency and the maximum displacement.
