Abstract
This paper describes the results of a detailed investigation of operating conditions on the hold-up of material in a rotating drum. It was found that the hold-up increases linearly with increasing feed rate, decreases linearly with increasing slope of the drum, and behaves in a complex manner with increasing drum speed. The combined effect of some of these operating variables on the hold-up was also studied and interpreted in terms of the type of flow of material in the drum. A semi-empirical model was adopted to predict the hold-up of material in a horizontal rotating cylinder with an end constriction.
