HFlow 1

1. Measurement: Bulk Density and Flow Rate

The HFlow 1 measures both bulk density and flow rate in pharmaceutical and metal powders, offering a choice of three standard funnels—Hall, Carney, and Gustavsson. Complied with USP, Ph. Eur., ASTM, and ISO standards, it accommodates diverse applications, allowing customers to choose the best fit for their measurement requirements.

2. Measurement Procedure

• Bulk Density

• Flow Rate 

3. Application Example

Analyzing bulk density and flow rate of various metal powders applied in additive manufacturing  (AM).

Hall, Carney, and Gustavsson funnels equipped in HFlow 1 have different orifice diameters and angles respectively. They can be employed to test the bulk density and flow rate of a wide range of metal AM powders for evaluating printability.

4. Interoperability

The combination of the laser diffraction analyzer Bettersizer 2600 and HFlow 1 assists in balancing the particle size distribution and flow property of AM powders.

In the feedstock preparation process, undersized particles tend to aggregate, which can be detrimental to powder bed fusion processes. The agglomerates will impede the flow behavior of the powder by increasing interparticle friction.

Powder Characterization

Powder characterization includes flow measurements, morphology, particle size distribution, density, and chemical composition. Bettersize PowderPro Series instruments are mainly used for the analysis of the powder physical properties by testing items such as angle of repose and fall, angle of spatula (flat plate angle), bulk and tapped density, dispersibility, voidage and cohesion, angle of difference, compressibility, uniformity, flowability Index, floodability index, sieve size, angle of slide, etc.
