2021 Marinitsch SOLEX Bulk Solids Knowledge – Physical properties of bulk solids II – Flowability
The simple definition of flowability is the ability of a bulk solid to flow. But there is a scale between free flowing and non flowing. Further, the flowability is not an inherent material property. Rather, it is the result of material physical properties and/or the equipment that is used for handling, storing and processing.
However, knowledge about the flowability is highly relevant for any bulk solid handling equipment. Adverse effects such as bridging, funnel flow, or rat‐holing, for example, may occur with equipment that is not properly sized.
