This dataset contains experimental measurements of pellet-sinter mixtures in the draw-down test, which was conducted to investigate the flow and segregation behaviour of multi-component granular systems. The study examines the effect of varying pellet-sinter mass ratios (50:50, 75:25, and 25:75) and layering order (standard and reverse layering) on key performance indicators (KPIs), including mass flow rate, angle of repose, shear angle, and segregation.
Methodology:
The experiments were performed using a custom-built draw-down test setup, where a controlled discharge mechanism was used to release the granular mixture from the top box (hopper) into the lower box. Load cells were used to measure the mass flow rate as well as the discharged mass into the lower box, while digital image analysis techniques were applied to measure segregation in both horizontal and vertical directions. The angle of repose and shear angle were determined by taking photos at the end of the experiments and applying image processing techniques.
Techniques Used:
• Granular material handling: Controlled experiments on pellet-sinter mixtures.
• Image analysis: Post-processing using colour thresholding for segregation quantification.
• Load cells: Measurement of mass flow rate as well as the discharged mass into the lower box.
• Statistical analysis: Data processing and calculations of confidence intervals.
This dataset provides a valuable resource for researchers in the field of granular materials, discrete element modelling (DEM) validation, and industrial bulk material handling applications. The data can be used to reproduce the findings, validate numerical simulations, and explore further aspects of granular segregation and flow dynamics.
