Bulk density The bulk density of a material is the weight per unit of volume (kg/m3 or lb/ft3), measured when the sample is in a compacted condition. This vibrated or settled density is used with the surcharge angle for determining the volume of material conveyed on the belt. Loose bulk density Loose bulk density is the weight per

Soil bulk density (SBD) is one of the important indicators that reflects soil quality and productivity (Zheng et al., 2004, Suuster et al., 2011). Mining and dumping both use large-scale machinery that repeatedly compacts the land, resulting in excessive SBD, hindering revegetation and the effectiveness of reclamation technology (Cao et al ...
