【摘要】 圆锥破碎机是工业生产中广泛使用的通用破碎设备,主要应用于矿山、冶炼、建材、公路、铁路、水利和化工等工业部门。我国的圆锥破碎机发展水平缓慢,破碎机设备效率低下。为提高破碎机效率,并在破碎领域内节能降耗,需要深入研究圆锥破碎机。影响圆锥破碎机性能的因素有很多,包括破碎机结构因素、性能因素以及操作因素等。这些因素对圆锥破碎机的性能如破碎机生产率、破碎产品粒度、破碎机能耗等又有着不同的影响。为此需建立圆锥破碎机多目标优化模型对圆锥破碎机性能进行优化。论文首先介绍了圆锥破碎机的基本情况及圆锥破碎机性能参数优化现状,接着分析物料的破碎原理以及圆锥破碎机的工作原理,基于物料层压破碎原理及散体物料的运动特性,建立圆锥破碎机的生产率模型,并分析物料的破碎过程,基于总体平衡模型建立破碎产品粒度模型,在生产率模型及产品粒度模型的基础上建立圆锥破碎机的优化模型,针对破碎机多目标优化模型选用主要目标法求解,利用MATLAB软件进行优化程序设计。最后,运用Solid Edge软件对国产PYB 1200型圆锥破碎机进行三维建模,并将开发的优化程序应用于该型圆锥破碎机上,比较优化前后PYB 1200破碎机的工作参数数据及破碎性能数据,分析破碎机转速、进动角及闭边排料口尺寸对圆锥破碎机性能的影响。论文中圆锥破碎机的优化模型及优化程序可以为圆锥破碎机的实际生产提供具体的参考数据,也可以为改善圆锥破碎机性能的进一步研究提供可鉴之处。更多还原

【Abstract】 Cone crusher is a general broken equipment which widely used in industry, such as mine, smelting, building material, road, railway, water conservancy, chemical industry, etc. Since the cone crusher development in our country is very slow, also the crusher efficiency is low, it is necessary to study cone crusher in-depth, as to improve crusher efficiency, save energy and reduce consumption in broken field.There are several reasons influencing crusher performance, such as crusher structure, performance parameters and manipulation parameters. The parameters also have different effect on capacity, product size, and power consumption. So this requires the establishment of multi-objective optimization model to optimize cone crusher performance.The paper first introduces basic knowledge and the status quo of performance parameters optimization about cone crusher, then analyze material comminution principle and the working principle of cone crusher, establishes a productivity model based on interparticle breakage and the movement character of the mass, also studies material breakage process, establishes a product size model based on population balance model, uses mathematics model to build optimization model of cone crusher, solves the cone crusher multi-objective optimization function with major objective solution, designs the optimization procedure with Matlab software. Finally, the paper builds a three-dimensional model of domestic-type cone crusher PYB1200, applies the Matlab optimization programming on the PYB1200 cone crusher, analyze how rotary speed, eccentricity, close side setting(CSS) influence cone crusher performance based on the parameter data and performance data before and after optimization. The cone crusher performance optimization model and optimization procedure in the paper can be used to provide reference data in the actual production; also can support the further research in improving the cone crusher performance.更多还原
