【摘要】：本文基于总体平衡理论和层压破碎理论对圆锥破碎机的破碎产品质量和生产能力进行了深入研究，，进一步建立了基于圆锥破碎机生产能力的腔型结构参数优化模型，为改进和研制新型、高效、节能的圆锥破碎机提供一定的理论依据。本文主要工作和内容如下： (1)以单颗粒物料为研究对象，通过矢量法推导出单颗粒物料以滑动方式通过破碎腔的运动特性的解析表达式。 (2)基于总体平衡理论，对圆锥破碎机的破碎过程模型进行了深入研究，进一步通过理论分析实现了对物料破碎过程中粒度分布的预测。同时，对圆锥破碎机破碎产品针片率的经验模型分析，得出了给料平均尺寸和闭边排料口尺寸对产品针片率的影响。 (3)对计算生产率的新方法进行了理论推导，以PYB900圆锥破碎机为例验证理论模型的正确性，并对影响圆锥破碎机生产率的工作参数和结构参数进行了分析，得到了圆锥破碎机生产率与腔型结构参数之间的关系。 (4)基于对圆锥破碎机生产能力的研究，建立了以圆锥破碎机生产率为目标函数的腔型结构参数优化模型，利用Matlab软件对PYB900圆锥破碎机腔型结构参数进行优化求解，结合优化后的腔型结构参数采用图解法画出圆锥破碎机的基本腔型；进一步基于最小磨损理论对考虑动锥衬板磨损情况绘制出动锥曲线图。
[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.
