Abstract Process Engineering Aspects and Statics of Silo Design. Design of silos for flow is described, starting from the flow profiles developing during discharge. The respective flow profile depends on the flow properties of the bulk solids and on the silo geometry. Based on measured flow properties the determination of the maximum permissible hopper wall inclination to achieve mass flow and of the minimum dimension of the outlet to prevent arching and ratholing is demonstrated, taking into account time consolidation aspects. This yields the size of a feeder and the position of discharge aids. The flow properties are required additionally for structural design of silos. Flow of bulk solids in silos, especially the development of asymmetric flow channels, has a significant influence on the pressure distribution.
