COAL PHYSICAL TESTING - SGS

BULK DENSITY The bulk density of coal particles in a sample is the mass of the coal divided by the volume that the coal particles occupy. Tests are done in either small or large container formats. Un-compacted bulk density is not an intrinsic property of a coal pile as it can change depending on how the coal is handled, how much

THE EFFECT OF GRANULATION CONDITIONS ON BULK

2004-10-13  bulk density changes with the time of granulation. Zuurman et al. (1995) conducted studies on the effect of a binding agent on bulk density and compactibility of granules of two types of lactose, using two different wet granulation techniques. They found that efficiency of the binder increased with a decrease of bulk density of the granulated bed.
