Abstract
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%.
