According to the international standard ISO9136-2:19 99 (E), the technical requirements for" the measurement of the bulk density of the abrasive material,
Working principle : Place the tested micropowder in the funnel, and the micropowder will be stable under its own accumulation.When start the electromagnetic oscillator, under the action of electromagnetic vibration, micro powder will follow into the measurement cylinder in particular ways and methods, Scrape the micropowder which in measuring cylinder and make it leveling , weight the micropowder left in the measurement cylinder after leveling on the balance scale , then divided by the volume of measuring cylinder, your can measure the bulk density of powder under test
The inner diameter of funnel lower opening:28mm, cylinder volume: 200ml, funnel outlet height: 38mm, the dropping height of the measured powder: 140mm.
