Buy White Aluminum Oxide Abrasive 220 Grit

In accordance with the special requirements of sand-grinding, the shape of the white fused alumina particles is the best. The ideal particle shape is an α-Al2O3 single crystal crystal form, that is, a tetrahedral shape equal volume crystal form. Such aluminum oxide grit particles are sharp, difficult to peel off, and have a good grinding effect. In practice, the ideal particle shape is rare.

Starting from the white aluminum oxide grinding effect, it is expected that the particles of the abrasive are full, solid, and have an approximately equal volume shape with sharp corners. The best grinding powder for precision grinding is measured by the percentage of ideal particles. In a certain batch of green silicon carbide grinding powder, if it can have 50% of the ideal equal-shaped particles, even if it is very good, it is often not achieved in practice, and multiple sorting is required.


Alumina is the main raw material for smelting corundum because alumina contains a large amount of white corundum. Bauxite is also a very important economic mineral, and it is the main source of aluminum smelting industry. The grade of bauxite is divided according to the content of alumina. The aluminum oxide abrasive refractory industry and the cement industry also use alumina in large quantities, followed by the abrasive manufacturing industry and the chemical industry.


Because this kind of brown fused alumina price particles has sufficient strength and good long-lasting cutting performance, while other shapes (such as flake-type or sword-shaped) particles have poor embedding and embedding properties, and are prone to crushing and breaking. Sand grinding is not good. The other name of bauxite is bauxite, black silicon carbide which means it is rich in aluminum. There are three appearance characteristics of domestic bauxite.


The first is white to light gray, with a soft texture and high quality. The second is light gray to dark gray, white alumina which is relatively hard. The fractures are flakes, beans, or lumps. Obvious sedimentary rock characteristics; the third is light yellow to ochre, the hardness and fracture shape are similar to the second, but the synthetic corundum structure is relatively thin, and most of the grade is not as high as the first two. 


The quality of black corundum bauxite is difficult to judge by appearance characteristics, because the metallogenic environment varies greatly from place to place, the following three points of identification experience are for reference only: those with a bean-shaped structure at the fracture, good quality, and the emery abrasive content is expected to be above 75%; The color is light, the color is good; the structure is fine and dense.


 53% After detection, the C content in the pink corundum synthesized using the aluminum ash treated by this method was 0.13%, while the C content in the white aluminum oxide 120 grit synthesized using the aluminum ash not treated by the method was 0.53% in the comparative example. The carbon content was reduced by 75.5%. China has extremely rich bauxite deposits. Large-scale new mines are constantly being discovered. 


In our province alone, 800 million tons of new silicon carbide abrasive mineral resources have been submitted in three years. The petrographic composition of alumina is mainly gibbsite, which means that alumina is in alumina. The ore is in the form of gibbsite, in addition, a part of it is combined with silica to form kaolinite. During the brown fused alumina grit smelting process, the water flow during rinsing should not be too fast to prevent a large amount of free carbon from being washed away.
