discharge rate through the bin outlet. It may seem strange that the same fine powder which can flood through an outlet uncontrollably in a funnel flow bin can, at the same time, flow through a mass flow bin at a rate which is lower than desired for process requirements. The reasons for these phenomena will be described below. 2.3 Segregation
