Particle Classification Simulation in a Centrifugal-Type Air Classifier

概要

論文の詳細を見る
A forced vortex-type centrifugal air classifier has the advantages of fine cut-size and high classification accuracy. It's capacity for classifying submicron particles attracts attention. Various types of classifiers are on the market. However, the classification mechanism has not been clarified. We describe simulation of particle motion in a classifier. Effects of the initial angular position and circumferential velocity of a particle at injection into the classifier and of capturing accuracy are also discussed, based on results of particle trajectories.
