Tap Density Tester

I. Product Introduction

The Tap Density Tester is a high-precision instrument that precisely determines the density of powders or granular materials in the tapped state by simulating the vibration conditions of actual working conditions. Its core function is to evaluate the volume change of materials during the compaction process, providing key data support for industrial production, R&D and quality control.

II. Application Scope

Widely used in the defense industry, papermaking, cement, battery, coating and various metal and non-metal industries, it is an ideal instrument for density testing. Metal powders: aluminum powder, zirconium powder, nickel powder, tungsten powder, tin powder, zinc powder, molybdenum powder, magnesium powder, copper powder and other rare metal powders. Non-metal powders: talc powder, kaolin, calcium carbonate, coal powder, phosphor powder, brucite, calcite, wollastonite, tourmaline, diamond, barite, fluorite, zeolite, boron carbide, clay, graphite, quartz, gypsum, bentonite, diatomite, zirconium silicate, corundum, mica, clay, titanium dioxide, etc.

III. Applicable Standards

1. GB/T 5162-2021 / ISO 3953:2011 Metallic powders - Determination of tap density.

2. GB/T 21354-2008 / ISO 3953:1993 Powders - General method for the determination of tap density.

3. ISO 787-11 Determination of tamped volume and apparent density after tamping.

4. Chinese Pharmacopoeia 2020 edition.

IV. Tapping Principle

A measured quantity of powder is placed in a graduated cylinder. While maintaining the original shape of the particles, a vibration device moves the cylinder uniformly back and forth in a straight vertical motion so that the gaps between particles approach a limit value, until the volume of the powder no longer decreases. The mass of the powder divided by the tapped volume gives the tap density of the sample.
