Product Details

Micro silica,Sika fume, production method introduction:


There are many ways to produce finished Micro silica from silicon blocks. 

The effect is better, and the application is more: ball milling method, roller grinding method, and swirling method. The main equipments: ball mill, roller mill and swirling machine have different quality technical requirements in the milling. The first two are crush honing under gravity, and the latter is impact crushing. Various mills are non-flammable and explosive, and minerals with a Mohs hardness of less than 7.0 can be processed and crushed. The finished product size is controlled by the process and is controlled in the range of 30 mesh (0.613 mm) to 425 mesh (0.033 mm).
