[Abstract]:Based on the overall equilibrium theory and the laminated crushing theory, the quality and production capacity of the cone crusher are studied in this paper, and the optimization model of the cavity structure parameters based on the production capacity of the cone crusher is established.It provides some theoretical basis for improving and developing new type, high efficiency and energy saving cone crusher.The main work and contents of this paper are as follows:1) taking the single particle material as the research object, the analytical expression of the motion characteristic of the single particle material passing through the broken cavity by sliding mode is derived by the vector method.2) based on the general equilibrium theory, the crushing process model of cone crusher is deeply studied, and the prediction of particle size distribution in the process of material crushing is realized through theoretical analysis.At the same time, the influence of the average feed size and the size of the closed edge discharge port on the needle rate of the product is obtained by analyzing the empirical model of the needle rate of the broken product of the cone crusher.The new method of calculating productivity is theoretically deduced. The correctness of the theoretical model is verified by taking PYB900 cone crusher as an example, and the working parameters and structural parameters that affect the productivity of cone crusher are analyzed.The relationship between the productivity of cone crusher and the structure parameters of cavity is obtained.Based on the research on the production capacity of cone crusher, the optimization model of cavity structure parameters is established, which takes the productivity of cone crusher as the objective function. Using Matlab software, the cavity structure parameters of PYB900 cone crusher are optimized and solved.The basic cavity shape of the cone crusher is drawn by graphic method combined with the optimized cavity structure parameters, and the moving cone curve is further drawn on the basis of the minimum wear theory.
