涡流空气分级机内物料分布的模拟试验研究
Simulation experimental study of material distribution of turbo air classifier
摘要
Abstract
In order to research the rule of the material distribution in turbo air classifier, and find a method to solve the dispersion of the material in turbo air classifier, the spreading plate experiment was designed to simulate the material distribution in turbo air classifier, and the material distribution was researched through calculation and series of experiments. The standard sand for building was used in the experiment. The results demonstrate that the speed increasing of the spreading plate can improve the dispersion of the large particle materials but has less impact on the dispersion of the small particle materials; the particle size distribution of the materials has a greater impact on the material dispersion; the wider range of particle size distribution, the poorer the dispersion. Meanwhile, the effect of spreading plate structure on the material dispersion was researched. The results show that using two-layers spreading plate can reduce the area deposition from 0.067 g/cm2 using one-layer spreading plate to 0. 042 g/cm2and the relative reduction is 37.31％, thus improving the dispersion of the material in turbo air classifier.关键词
