Depending on the combination of hopper angle and wall friction angle, either mass-flow or funnel-flow discharge with the particular bulk material will result. Simply speaking, a highly frictional bulk solid, such as sand, will require a steep hopper angle to achieve mass flow, whereas a low-friction bulk solid, such as smooth catalyst beads ...
