3D scans, angles of repose and bulk densities of 108 bulk material heaps

This paper presents a dataset of spatial data, angles of repose and bulk densities collected from 108 bulk material heaps. The investigated materials were lignite, wood chips, limestone, blast furnace coke, fresh and dried corn grains, milk powder as well as bituminous coal. Sample sizes range from 16 liters to approximately 220 liters, and each measurement was repeated four times to allow for variance assessment. This dataset is particularly useful for researchers and engineers, who want to investigate the shape of bulk solid heaps, or who want to test or benchmark measurement methods concerning heaps of granular matter, such as the angle of repose.
