coal mill model parameters

Mar 01, 2020· The classification performance of a model coal mill classifier with non-swirling and swirling inlet conditions of the bottom incoming flow was experimental and numerically studied. The PIV measurements showed that under different inlet conditions, the flow fields adjacent to two neighboring blades were very different.
