COAL PHYSICAL TESTING SGS

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
