Bulk Density


Bulk density is defined as the weight per unit volume of material. Bulk density is primarily used for powders or pellets. The test can provide a gross measure of particle size and dispersion which can affect material flow consistency and reflect packaging quantity.

Test Procedure:
A funnel is suspended above a measuring cylinder. The funnel is filled with the sample and allowed to freely flow into the measuring cylinder. The excess material on top of the measuring cylinder is scraped off with a straight edge. The sample and the cylinder is then weighed and the weight / volume (Bulk Density) is determined.

Specimen size:
Powder or Pellets

Apparent density value is recorded as g/cm3

Equipment Used:
Graduated Cylinder
Mettler Balance
