New approach to ball mill modelling as a piston flow ...

2018-1-15  This paper presents a new population balance model (PBM) of ball mills that understands the ball mill process as a hybrid of a perfectly mixed mill and piston flow mill. Usually, PBM for grinding is related to a perfectly mixed mill. In this case, the piston flow was introduced for a more realistic process.
