[Abstract]:Conical crusher is a kind of material crushing equipment, which has the advantages of low energy consumption and high comminution efficiency. It is widely used in road, construction and mining industries. As far as the research of cone crusher is concerned, how to increase productivity, reduce energy consumption and increase service life is the focus of attention. The crushing force of crusher affects the working performance of equipment. The study of crushing force is of great significance to the analysis of the dynamic performance of the whole machine and the wear analysis of the broken parts. In this paper, the existing crushing force calculation methods and their shortcomings are analyzed. Based on the actual crushing test, a multi-factor model for calculating the crushing force is established. This paper provides a method for the analysis of the working performance of the cone crusher and the optimum design of the cavity shape. Firstly, based on the working principle of laminated crushing of the cone crusher, the movement of the bulk material and the stratification of the cavity in the chamber are analyzed. The key influencing factors of extrusion crushing force are discussed. The crushing behavior of crusher was studied in depth. The influence of three factors on crushing force, such as compressive strength, compression ratio and particle size distribution, was analyzed, and the mathematical model of three factors influencing crushing force was established. Secondly, using the rock mechanics test system to carry on the mechanical test research to the rock material extrusion crushing process, carries on the regression analysis to the test data, solves each parameter in the extrusion crushing force mathematical model. Based on the case of material stratification, the distribution of crushing load is solved in detail. The distribution of crushing force in crushing cavity is compared with that in actual production by using the mathematical model of crushing force to verify the accuracy and reliability of the model. Finally, the virtual prototype model of the cone crusher is established by using Adams software. The extrusion force is used as the input of the simulation model. The kinematics / dynamics results of the crusher under different materials are simulated, and the rotational speed of the moving cone and the friction load are obtained. In order to determine the optimal structural parameters and working parameters in the design phase. The establishment of mathematical model and mechanical simulation analysis of the crushing force of cone crusher provides the basis for the structural design and kinematics simulation analysis of the crusher. It has important guiding significance and reference value for further development and optimization design of crusher.
