FEM 2.312 - Discharge of Bulk Material from Silos Description and Assessment of Discharge Systems

FEM 2.312-EN

This document is intended to illustrate the interrelationship between the properties of bulk material, silo operation and discharge system. It is intended to make clear to planners, manufacturers and operators of silo systems the criteria for selecting a suitable discharge system.

The characteristics of bulk materials, such as for example grain size or temperature, must be taken into account when designing the discharge system. The flow capacity of the bulk material is of special importance (see document FEM 2.381). Since discharge systems should be well-matched to the bulk material to be discharged, it is recommended to describe the bulk material with great accuracy (see document FEM 2.581/2.582). The description of bulk material properties according to FEM 2.581/2.582 helps identify the bulk material and this identification may be helpful in looking for the appropriate discharge system.
