White fused alumina density classification,

White fused alumina density classification,
One is the bulk density of white fused alumina, and the other is the true density of white fused alumina.
The bulk density is: 1.53–1.99g/cm3. The bulk density of the abrasive is related to the particle size, particle size composition, variety, particle shape and other factors. Generally speaking, the bulk density of the coarse-grained abrasive is larger than that of the fine-grained abrasive. The bulk density of the abrasive is greater than the density of a single particle size.
The true density is: 3.95~4.0g/cm3, the true density of the abrasive refers to the basic particle size of the abrasive contained in the unit volume (the volume excluding the open pores): 65%, the basic particle size is an important indicator to ensure the grinding effect. It should be properly controlled during production, but the production speed may slow down.
