White corundum fine powder and micro powder, some people always do not understand the difference between them. Some people also believe that there are two different specifications. Although this understanding is not too big, it is very different from the truth. So what is the difference between white corundum micropowder and fine powder?

White corundum fine powder refers to white corundum mixed sand. The basic items we commonly use are 180-0 mesh, 220-0 mesh, 240-0 mesh and 325-0 mesh. Different models have a variety of specifications. In contrast, white corundum micropowder is different. The type refers to the single particle size of the powder, which is roughly W5, W7, W10, W15, W20, W63, etc.
In terms of production technology and processing technology, the two are also different: the production of fine powder is generally carried out by ball milling, air separation and other steps, because the crushing time is long in the production process, so it will appear relatively white. However, generally in the air separation process, the impurities in the powder will be directly removed, so in the actual use process, it will not affect its performance. In the production process of micropowder, there are usually two steps of cleaning and pickling, so the impurities generated in the production process will be cleaned in a small amount through these two steps.
The price of white corundum micropowder is also different from that of fine powder. The price of micro powder is much higher than that of white corundum fine powder. This is mainly because micronized powders still require screening and subsequent processing. Through different screening, white corundum sand with different particle sizes is screened out. The process is difficult and the cost is high. There are also many. High prices are natural.
