FT-102A振动漏斗松装密度测定仪
FT-102A vibrating funnel bulk density measuring instrument
一、参照标准Meet standards：SJT 10215-1991   ISO 3923/3  GB/T5061-1998
二、适用范围Scope of application：
适用于不能自由流过孔径为5mm的磁性氧化物粉末松装密度的测定， 同时适用于类似粉末松装密度的测量；不适用于在振动过程中易碎裂的粉末，如针状和纤维状。
applicable to the determination of the bulk density of magnetic oxide powders, which cannot be freely flowing through 5mm aperture, and it also suitable for measuring the bulk density of similar powder; do not apply to easily broken powder in the process of vibration, such as needle and fibrous powder.
三、原理Principle：
振动漏斗法--在规定的条件下振动，使粉末从漏斗中自由降落，充满已知容积的圆柱杯内，以单位体积粉末的质量表示粉末的松装密度。
vibrating funnel method -- Vibration under specified conditions, the powder free landing from the funnel in a certain height, full of known volume of the cylindrical cup, the mass of powder per unit volume is used to represent the bulk density of powder.
