The fineness of micro-silica fume is less than 1μm, accounting for more than 80%, and the average particle size is 0.1-0.3μm, which is a gray state. Therefore, the bulk density is small, the natural inclination angle is large, fluffy, easy to fly, and difficult to store and transport. It is because of these characteristics that micro-silica fume manufacturers need to be more careful when handling them. So, what is the specific treatment process?
