　　White corundum fine powder mainly refers to white corundum mixed sand, which is generally used in the range of 325-0 mesh. Depending on the needs of different industries, the specifications used are also different. White corundum fine powder refers to white corundum mixed sand. The basic items we commonly use include 180-0 mesh, 220-0 mesh, 240-0 mesh, and 325-0 mesh. Different models have various specifications. In contrast, white corundum micro powder is different. The main types refer to the single particle size of the powder, roughly W5, W7, W10, W15, W20, W63, etc.

　　In terms of production processes and processing techniques, the two also differ: the production of fine powder generally involves processes such as ball milling and air separation. Due to the longer crushing time during production, a relatively white condition may occur. However, during the air separation process, impurities in the powder are directly removed, so it does not affect its function during actual use.

　　In the micro powder production process, there are usually two processes: washing and acid washing. Therefore, impurities generated during production will undergo minor cleaning through these two processes (if any).

　　White corundum micro powder and fine powder not only have certain differences but also differ in Price; the Price of micro powder is much higher than that of white corundum powder. This is mainly because micro powder still requires screening and subsequent processing. Different particle sizes of white corundum sand are screened out through different screenings. The process is complex, and the cost is high. Therefore, a high Price is quite natural.
