Dynamical Property, Loci and Separating of Materials in Inclined Airflow Device

Based on the research of the dynamic equation of material in inclined airflow, more precise dynamic model was developed in the article. By means of numerical evaluation, motion loci of materials, single factor relation curve of the airflow velocity and material velocity were calculated in the grain cleaning chamber of inclined airflow. And by the analysis of the curves, the article points out how to adjust the parameters and to make an airflow cleaning device to optimum work conditions in practice.
