Tap density tester is defined as containing the powder in the container under the conditions specified by tap density after.
According to international GB/T5162-2006/ISO 3953:1993 (metal powder tap density determination), and with reference to the United States Pharmacopoeia independent R & D manufacturing of powder density testing equipment with independent intellectual property rights. Instrument covers the national standard GB T 5162-2006 ISO3953: 1993 in the indicators. For non-metallic powder, powder tester extends the density of some features, such as: 'vibration amplitude' provided by the national standard 3mm integral extended to 1mm ~ 10mm adjustable; 'frequency'was set forth by the national standard of 100 ~ 300 times / minutes adjustable, extended to 0 ~ 300 times min adjustable. Powder density tester from the adjustable speed motor, vibration components, microcomputer and micro-printer parts. And instruments with a compact, solid, simple operation.
