The principle of the determination of the fee-flow bulk density consists in pouring a sample through a specified funnel into a specified receptacle of known volume and weighing the contents of the receptacle. In order to determine the compacted bulk density a volume of a given mass of the product shall be measured after a fixed number of taps (usually 300) in a tapping volumeter. Three figures show suitable apparatus.
