Natural bulk density meter with variational funnel method

Product Introduction

The natural bulk density meter (variational funnel method) is designed and produced in accordance with the national standard GB/T 16913.3-2008.Used for determination of dust accumulation density.

Widely used in various metal powder, nonmetal powder, chemical powder such as powder metallurgy powder, magnetic material powder, alloy powder, milk powder, abrasive, coating, food additive accumulation density test

Principle: dust falls freely from the funnel to fill the measuring cup at a certain height;The mass of dust per unit volume in the measuring cup under loose loading condition is measured, that is, dust accumulation density.

Instrument structure

1. Funnel (flow outlet diameter: 12.7mm) : the funnel is made of stainless steel, in which the taper of the funnel is 60°±0.5
2. Blocking rod: stainless steel material, used to prevent dust falling down when dust is put into the funnel.

3, measuring cup, this device is equipped with a volume of 100 ml stainless steel cup, cup inner diameter for Φ 39 mm.

4, scraper: stainless steel, used for dust into the funnel when the removal of excess dust.

The determination of steps

1. Test the weight m1 of an empty stainless steel measuring cup
2. Plug the funnel with a stick and weigh some powder into the funnel
3. Unplug the plug and leave the powder free downstairs until it completely overflows the measuring cup
4. Use a stainless steel ruler to level off any excess powder in the measuring cup and weigh the cup and powder to m2
5. Calculate the powder deposition density according to the formula: =(m2-m1)/V remark: V corrected volume of measuring cylinder, 100cm3.

Note: The difference between the maximum and minimum dust mass value obtained from three consecutive measurements should be less than 1g, and the average value of three measurements meeting the requirements should be taken as the measurement result.

Standard configuration: densitometer main engine plug rod cylinder measuring cup scraper brush
