1 Importance and range of bulk density measurements Bulk density, also called an apparent density, is defined as the mass per unit volume of loosely piled granular material (eg. coal or coke). The coal bulk density depending on its particle size, impurities, moisture may be in the range of 700 to 1100 kg/m3. The bulk density varies depending on ...
