The Natural Bulk Density Meter is on the basis of natural accumulation of the  provisions of the national standard GB/T 16913.1-1997 to design  and production. The utility model is suitable for the determination of bulk density of dust. Sample collection please refer to GB/T 16913.1-1997 dustphysics  experiment methods--Part first: the relevant provisions of  the collection  of  dust  samples.

Let powder freely fall from the aperture of the funnel at specific height until fill up the measuring cup, weigh the bulk powder in specific volume, which is  the bulk density.
