The bulk density of white aluminum oxide
The bulk density of white aluminum oxide is a key index for abrasive production. Bulk density refers to the mass (weight) of abrasive in unit volume under the condition of natural accumulation. It is called LPD means loose pack density.
The bulk density of white aluminum oxide is a composite index of specific gravity, grit shape, and particle size distribution. The LPD of abrasive grit impacts the forming performance of abrasive tools, the strength of abrasive products, and the porosity of abrasive tools. In the meantime, It affects the grinding life, sharpness, and other index performance of grinding wheels and abrasive tools.
The main factors affecting the bulk density of white aluminum oxide include:
- Effectively control the distribution of abrasive particle size composition and adjust the proportion of basic particles and mixed particles, coarse particles, coarsest particles, and fine particles.
- Select a reasonable sand-making process to make the grain shape of white corundum sand as appropriate as possible. The milling process of Barmac and ceramic ball always get higher bulk density.
- Improve the bulk density of abrasive by shaping. The shaping process can make the abrasive particles more round and reduce the gap space in the middle of the particles.
Of course, not all abrasive products need higher density. Abrasive wheels manufacturers can choose the proper bulk density of white aluminum oxide to get ideal performance.
