Analysis Of Cone Crusher And Cavity Type Structure Optimization Design

Crushing equipment is widely used and the broken technology innovation depends on the progress of human society and the development of science and technology. After several decades of development, the domestic crushing equipment has reached a higher level on the shape and the structure, but far from the most advanced far abroad ones on the performance. In order to promote the progress of domestic crushing technology and to achieve the goal of improving the crushing performance, the research point of this paper project is aimed to guide its cavity structure optimization by analyzing the movement characteristics of cone crusher under the support of cooperation projects of guangdong shaoguan lei heavy machinery manufacturing co., LTD. Based on the research achievements of domestic and foreign scholars, project design of PLM1500I machine which is designed by our team is selected as the research object. The full text starts the study from the perspective of PLM1500I machine work mechanism and the movement characteristics, and it relates to working principle, the device structure designing characteristic, movement characteristics, crushing processing model, predicting distribution model of product particle size and cavity structure multi-objective optimization model of PLM1500I machine.(1) Based on the working principle of PLM1500I machine and the kinematics and dynamics analysis of mixed coexistence of three movement mode of falling mineral stone, mathematical model of its movement is built which characterizes affection of PLM1500I machine working performance caused by stone movements. The simulation experiment verifies the fact that the Ore stone of free fall model have the most times of extrusion and the highest production capacity, while mineral stone of sliding movement mode have the least times of extrusion and the lowest production capacity.(2) Based on the balance theory model of particle size-mass, the hierarchical broken features and on broken process analysis of the mineral stone in PLM1500I cavity, the mathematical model in the crushing process is built which characterizes the particle size distribution of finished product and prediction and the effect on particle size distribution caused by the main structure parameters of PLM1500I equipment. The simulation experimental shows the availability and correctness of the mathematical model. It forecasts the size distribution, and verifies the existence of one most value of rotating speed of eccentric sleeve of PLM1500I machine. It prove the fact that the relationship between particle size and broken cone diameter D with precession Angle Y is increasing nonlinear, and the relationship between particle size and crushing cone base Angle uB, the swing stroke st,the closed edge discharging mouth size Css and parallel zone length 1. is diminishing nonlinear.(3) Based on the research on working principle and movement characteristics of PLM1500I machine, a multi-objective optimization model of PLM1500I is built which includes the production capacity, the working performance of cavity model, the product particle size after broken and the and wear-resisting cavity model, and the method of main target is adopted to solve the multi-objective optimization problem and the optimized cavity type structure is finally obtained. In addition, the influence of PLM1500I equipment production capacity caused by different optimization schemes sing studied which verifies the correctness and availability of multi-objective optimization model.
