The assumption that a smooth wall finish, such as stainless-steel mill finish as opposed to carbon steel, will give mass flow in a less steep cone is not always valid. This paper presents case studies of how the kinematic angle of friction (φ′ ) between dry bulk solids and bin walls affects the design of mass flow hoppers and how it varies for different materials.
