Powder density refers to the mass corresponding to a unit volume of powder. Due to the presence of voids (or pores) between particles or within particles in the powder, the density of the powder is usually lower than the true density of the corresponding substance. Powder density can be divided into bulk density (also known as bulk density) and tap density according to different testing methods. Loose density refers to the loose state of a powder sample, which is uniformly and continuously filled with a known volume of measuring cup. By weighing the mass of the measuring cup and the powder sample, the loose density of the powder sample can be calculated. The compacted density refers to the density of the powder contained in a container after being compacted under specified conditions.

HR—D3 型Powder density testerIt is based on our companyNational standard GB/T 5162-2006/ISO3953:1993（The determination of the compacted density of metal powder is conducted using a powder density testing instrument independently developed and manufactured according to the United States Pharmacopeia, which has independent intellectual property rights.

Operation Method

During testing, place any amount of powder (not exceeding the Z-high mark of the measuring cylinder used) into the cylinder and keep it in place

Under the original form of the particles, the uniform reciprocating up and down linear motion of the vibration device is used to make the particle gap tend to be uniform

Limit value, until the volume of the powder no longer decreases. The mass of the powder is divided by the volume after compaction to obtain the sample

Vibration density.

Representation method:

ρ= m/v (g/cm³)

ρ: Compacted density

M: Sample quality

V: Volume of the sample after vibration compaction
