Dataset of laboratory experiments on cohesive iron ore bulk properties - in PhD thesis Grabs and Cohesive Bulk Solids
Wat erin zit
· Three bulk properties (type of cargo, moisture content, and pre-consolidation) are responsible for the variations of the dependent bulk properties. Various dependent bulk properties, including bulk density, angle of repose, penetration resistance, and shear strength were quantified. · The three iron ore samples are categorized as very cohesive to cohesive based on the ring shear test results. · A general conclusion is that the dependent bulk properties of cohesive iron ore samples are highly sensitive to the history of the applied stress, σ pre . This phenomena was observed in both ring shear and consolidation-penetration tests, in which high correlations between pre-consolidation and respectively flowability and accumulative penetration resistance are found. Therefore, choosing appropriate range of pre-consolidation in the design of equipment for handling cohesive iron ore is also crucial.
