Dry Bulk Solids: chemical
sugar powdered to urea granular
Flow and physical properties of dry bulk solids for hopper, bin, silo, chute, and conveyor design. Covers grains, aggregates, chemicals, plastics pellets, and biomass. Properties include bulk density (loose/packed), angle of repose, angle of internal friction, Jenike flow factor (ff), Hausner ratio, Carr compressibility index, cohesion class, and moisture sensitivity. Per Jenike Storage and Flow of Solids Bulletin 123, Schulze Powders and Bulk Solids, and CEMA Belt Conveyors.
