Description
GA-16913 Powder Packing Density Meter
Introduction
Natural packing density meter (variable funnel method) is designed and produced according to the national standard GB/T 16913.3-2008; Used for the determination of dust accumulation density.
Widely used in various metal powder, non-metal powder, chemical powder such as powder metallurgy powder, magnetic material powder, alloy powder, milk powder, abrasive, paint, food additives bulk density test
Principle:
Dust from the funnel mouth at a certain height free fall filled with measuring cup; Measure the mass of dust per unit volume in the measuring cup under loose loading condition, that is, the dust accumulation density.
Instrument structure
1, funnel (flow outlet diameter 12.7mm) : funnel made of stainless steel material, the funnel taper is 60°±0.5
2, plugging rod: stainless steel material, used to prevent dust from falling when dust is loaded into the funnel.
3. Measuring cup: This device is equipped with a stainless steel measuring cup with a volume of 100ml, and the inner diameter of the measuring cup is Φ39mm.
4, scraper: stainless steel, used to remove excess dust when the dust is loaded into the funnel.

Determination procedure
1. Test the weight of the empty stainless steel measuring cup m1
2. Plug the funnel with a clogging rod and pour some powder into the funnel
3. Unplug the plug rod and let the powder free downstairs until the powder completely overflows the measuring cup
4. Scrape the excess powder of the measuring cup with a stainless steel ruler, and then weigh the weight of the measuring cup and powder m2 at this time
5. The packing density of powder is calculated according to the formula: ρ=(M2-M1)/V Note: the volume of the measuring cylinder after V correction is 100cm3.
Note: The difference between the maximum value and the minimum value of dust mass obtained by 3 consecutive measurements should be less than 1g, and the average value of 3 measurements meeting the requirements should be taken as the measurement result.
Standard configuration: densitometer host plug rod cylindrical measuring cup scraper brush
