We will see that all modern process for manufacturing bulk silica glass involve the preparation and viscous sintering of small, amorphous (glassy) silica particles. How this viscous sintering is accomplished, effects the purity and homogeneity, both chemical and structural.
Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. One of the most beneficial uses for silica fume is in concrete. Because of its chemical and physical properties, it is a very reactive pozzolan. Concrete containing silica fume can have very high strength and can be very durable.
In the silica powder making process, Jaw Crusher is used as primary crushing machine, then go through the secondary crushing plant. 2. The sand particles that meet the requirements enter into the sand making machine for making fine sand, while the others enter into the tertiary crushing plant for fine crushing, then go for sand making.
