Abstract
During the sand-making process, the wear of the split cone will affect the dynamic balance of the rotor and the sand-making effect of the crusher. This paper focuses on experiments and simulations with the rotor of a vertical shaft impact crusher. A wear model for predicting the wear value of the split cone is established and its effectiveness is verified. The orthogonal test of L 16 4 4 is designed. By using the range analysis method, the influence of the rotor speed, the feed height, the installation angle, and the number of the guide plate on the wear resistance of the split cone are studied. By using the multiple linear regression analysis method, the optimal parameter combination of each factor is obtained. The results of this paper show that the wear resistance of the split cone is the best when the installation angle of the guide plate is 40°, the installation number of the guide plate is 3, the rotor speed is 2800 r/min, and the feed height is 40 mm.
Highlights
Relevant researchers have carried out related work through experimental and simulation research methods and achieved good results
Zhang and others [12] used the discrete element method and regression analysis method to optimize the structural parameters of the rotor to improve the acceleration effect of the rotor on the particles
It is mainly composed of spindle assembly, motor, rotor, crushing cavity, feed hopper, and control system. e three-dimensional model of the rotor is shown in Figure 2, which is driven by the spindle of the vertical shaft impact crusher. e rotor is mainly composed of a feeding ring, split cone, guide plate, and upper and lower wear-resistant plates
Summary
0.07 each area of the split cone were the experimental wear value.
