The density of white corundum is divided into two types,
One is the bulk density of white corundum, and the other is the true density of white corundum. The bulk density is 1.53~1.99g/cm3. The bulk density of abrasives is related to the particle size, particle size composition, variety, particle shape and other factors of the abrasive. Generally speaking, The bulk density of coarse-grained abrasives is higher than that of fine-grained abrasives, and the bulk density of mixed-grained abrasives is greater than that of a single particle size. The particle density is: 3.95~4.0g/cm3. In recent years, the true density of corundum for precision casting of Henan Sicheng Grinding Technology Co., Ltd. Reach 4.1g/cm3.
The true density of the abrasive refers to the quality of the basic particle size of the abrasive contained in the unit volume (excluding the volume of the open pores): 45%~55%. The basic particle size is an important indicator to ensure the grinding effect, and it should be properly controlled during production. Production may have slowed.
