摘　　要：为了分析陶瓷干法造粒机叶片安装高度对造粒效果的影响,该文基于欧拉—欧拉模型建立数学模型,利用有限体积法求解,模拟研究了造粒过程中颗粒的体积分布情况。结果表明:当叶片与造粒室底端最小距离为15 mm时,颗粒的分散性最好,造粒效果最佳。In order to analyze the effect of the blade installation height on the granulation performance of a dry granulator, a mathematical model based on the Eulerion-Eulerion concept was established. It used the ifnite volume method and simulated the particle volume distribution in dry granulation process. Results show that particles dispersion and granulation result were the best when the minimum distance between the blade and the granulation chamber was 15 mm.
