Tap Density Tester Principle

The loose bulk powder is loaded into a graduated measuring cylinder to measure the sample volume. Fix the measuring cylinder on the tapped assembly.

Move the bottom of tapped assembly through eccentric gear according to frequency and height specified by international standards so that the measuring cylinder vibrates up and down. The volume of powder in the measuring cylinder can be reduced to different degrees according to its own physical characteristics.  The sample tapped density can be obtained by dividing the mass of sample by the volume after tapped.
