Aluminum Oxide Abrasive Blasting Grit Price

The difference between the raw materials for smelting brown corundum and white corundum: the main raw materials for smelting brown corundum are bauxite, coke (anthracite), and the main raw materials for smelting white corundum are: the difference between the uses of industrial aluminum oxide brown corundum and white corundum.

white fused alumina is mainly used for grinding wheel, sandblasting, free grinding, resin abrasive, coated abrasive, functional filler, filter medium, refractory white corundum To be used in: ceramic manufacturing, resin bonded abrasives as well as sandblasting, polishing, grinding, precision casting and advanced refractories. Density difference between artificial corundum and white corundum:


in the current national standard, the density of brown corundum and silicon carbide price is not less than 3.90g/cm3 from F4 (P12) to f220p (220), and not less than 3.85g/cm3 from f220p (220). In practical use, the indexes often used to judge the quality of corundum are generally the alumina content, particle size and hardness of corundum, and the density of corundum is rarely mentioned, while the density of general aluminum oxide blasting abrasive has two kinds of density statements: bulk density and true density. 


The bulk density is measured by filling a container white aluminum oxide particles, while the true density is measured in vacuum state. Let's take the bulk density and true density of white corundum under the condition of 44% ~ 55% of basic particle size as an example: the bulk density of white corundum: 1.53 ~ 1.99g/cm3, the mass of white corundum / container volume (including voids) and the true density of white corundum: 3.95 ~ 4.0g/cm3, the mass of aluminum oxide abrasive blasting grit / container body Volume (excluding pore volume)


In fact, the formation process of plate-shaped green carborundum is the process of crystal transformation and abnormal grain growth of alumina powder itself, and most of impurities remain in the product. After sintering, products with different particle sizes can be obtained by cooling, synthetic corundum price picking and selecting (picking out over burnt and under burnt products), inspection (physical and chemical index inspection side for sintered products), crushing and screening.


Under the current situation of high price of alumina powder, comparative analysis and research are made on the silicon carbide companies production and manufacturing cost and product performance of plate-like corundum. If domestic alumina powder can be fully used or partially used to replace imported alumina powder, it will not only have certain effect on production enterprises Guiding significance, but also for the whole alumina grit industry is a useful reference.


Using Bayer process light burned arc fused alumina powder as raw material for continuous ball milling, the fineness and specific surface area need to meet certain requirements, which is conducive to the sintering and densification of alumina powder. The milled powder is formed into a ball by a ball forming disc or a ball forming cylinder. After forming, the green ball should have a certain strength to avoid cracking in the 120 grit aluminum oxide harbor freight process of transportation to the dryer.


Therefore, the quality of raw materials of alumina powder determines the quality of plate-shaped fused alumina products. At present, imported industrial alumina powder is widely used as the main raw material in the production of plate-like corundum. In order to solve the problems of high moisture content, easy stratification and difficult drying in the 220 grit aluminum oxide blast media process of pelletizing, the corresponding process optimization design was carried out.
