| Resumo: |
Several methods were developed to assess the flowability of bulk material. Jenike introduced flowability values toassess the flowability of bulk material like mineral raw material under given loads. A method developed by Carr usesseveral granulometric parameters to describe the flow properties without influence on the load. The aim of the own studywas to evaluate the recommendations of Jenike and Carr regarding to their application onto crushed grain. Thereforemeasurements with grainy and powdery grain products were carried out to determine flow properties regarding Jenike andCarr. Additionally unloading tests with a level model silo were performed to find out the influence of the outlet diameter.The evaluations of the flow properties according to Jenike and Carr deliver partially different textual evaluations. Theflowability to Jenike and the flow index according to Carr drop abruptly in the range Q3(0.2 mm) = 5% ... 20%. This showsthat the flow properties are mainly influenced by their share of cohesive fines. A classification of the flow propertiesaccording to Jenike is more realistic for crushed grain.
