616 BULK DENSITY AND TAPPED DENSITY 松密度和紧密度 The bulk density of a solid is often very difficult to measure since the slightest disturbance of the bed may result in a new bulk density. Moreover, it is clear that the bulking properties of a powder are dependent on the “history” ...

used as an index of the ability of the powder to flow. The bulk density often is the bulk density of the powder “as poured” or as passively filled into a measuring vessel. The tapped density is a limiting density attained after “tapping down,” usually in a device that lifts and ...
