White corundumGranular sand
White corundum grain size sand can also be called single sand, its particle size range is generally F12-F220, such as F12, F30, F54, F90, F100, F220, etc., white corundum sand is a kind of particle size sand, these two models of products are mainly used in abrasive and other industries. White corundum granular sand also has the characteristics of acid and alkali corrosion resistance and good toughness, and can be used to make white corundum grinding wheel with the addition of some adhesives.
White corundum fine powder
White corundum fine powder is made from electrofused white corundum through a special processing process. It has the characteristics of high hardness, slightly lower toughness, strong grinding power, high purity and good self-sharpening, while white corundum fine powder is mostly white.
Commonly used particle sizes are 180-0 mesh, 220-0 mesh, 240-0 mesh and 325-0 mesh. It can also be called mixed sand, taking the aforementioned 240-0 mesh as an example, it refers to white corundum abrasive containing more than 240 mesh mixed particle size, and does not refer to the particle size of all products are 240 mesh.
From the use of white corundum, it is not only an abrasive for making abrasives, a material for grinding and polishing, but also a refractory material, so you will often hear white corundum abrasives, white corundum abrasives, white corundum refractories and so on. Abrasives processed with white corundum fine powder are suitable for grinding high carbon steel, high speed steel, and various stainless steels, and can also be used in casting, steel refractories, ceramics, military, electronics and other industries.
White corundum powder
The specifications of white corundum powder are relatively simple compared with the previous types of products, and its specifications are generally relatively single particle size powders, and the main particle sizes can be divided into W5, W7, W10, W15, W20, W63, etc. Its later process needs to add multiple screening treatments to ensure that the particle size of white corundum sand meets the requirements of micronized products, because this process is more complex and laborious, resulting in a significant increase in the required production costs, so the price of white corundum produced is more expensive than other white corundum products.
