Abstract:
Granular materials are of great interest in today’s world due to their usage in several industries, starting from food production to pharmaceuticals. Hoppers, silos and bins are equipments that are designed to store/transport the granular materials. Hoppers, being the most common, are subjected to various flow issues. These flow issues might lead to delays in running the plant, process downtimes, and material wastage. Hence, characterizing the flow issues is important to understand the behaviour of the materials. In this work, I am characterizing glass beads to understand their flow issues using one of the most commonly used yet effective ways of determining the flow nature of the material under study, i.e. Angle of Repose (AoR). Two ways of calculating the AoR are used to better understand the variability in the way of measurement. It is clearly noted from the study that the highly cohesive particles tend to have higher angles of repose/cannot be determined in some cases due to their poor flowability.
