The bulk density of a powder is the ratio of the mass of a powder sample and its volume.The bulk density is expressed in grams per mL(g/mL) or g/cm3. It is divided into loose bulk density and tapped bulk density. The bulk density of a powder is often very difficult to measure with good reproducibility. LaBulk is a place to know more about bulk density including buk density equipments, bulk density apparatus
, bulk density testers
, scott volumeters, bulk density funnels, tap density testers
, as well as bulk density testing methods, bulk density measurement,determination of bulk density of powders. LaBulk is a famous brand of HMK Test concerning bulk density.The total bulk powder volume includes particle volume, inter-particle void volume, and internal pore volume.Bulk density is not an intrinsic property of a material; it can change depending on how the material is handled.The bulk density of powders is usually reported both as "freely settled" (or "poured" density) and "tapped" density (where the tapped density refers to the bulk density of the powder after a specified compaction process, usually involving vibration of the container.
