This paper takes the valve-controlled clean water pump ore transportation equipment as the research object, and establishes the mathematical model and finite element model of the ore separator. Based on the calculation method provided by Computational Fluid Dynamics, the numerical simulation and experimental study of the solid-liquid two-phase flow process inside the ore separator is carried out. Furthermore, a single factor analysis method is used to analyze its working performance, separation and conveying efficiency. The change in particle concentration changes the flow characteristics of the internal flow field of the storage tank, increases the number of ore flowing into the separator per unit time, and ultimately affects the separation performance of the ore separator. With the increase of particle concentration, the ore separation efficiency η increases first and then decreases. When the particle concentration is 10%, the slurry separation efficiency is the highest, about 98.93%. With the increase of the particle size, the efficiency of ore particles flowing into the storage tank increases first and then decreases. When the particle size is 20 mm, the value of ξ is higher, reaching more than 92%.

本文以阀控清水泵输矿设备为研究对象，建立了选矿机的数学模型和有限元模型。基于Computational Fluid Dynamics提供的计算方法，对选矿机内部固液两相流动过程进行了数值模拟和实验研究。此外，采用单因素分析方法对其工作性能、分离和输送效率进行分析。颗粒浓度的变化改变了储罐内部流场的流动特性，增加了单位时间内流入选矿机的矿石数量，最终影响选矿机的分离性能。随着颗粒浓度的增加，η先增大后减小。当颗粒浓度为10%时，浆液分离效率最高，约为98.93%。随着粒度的增大，矿粒流入储罐的效率先增大后减小。当粒径为 20 mm 时，ξ值较高，达到 92% 以上。
