Silica is an inorganic substance and among the most important compounds of silicon. It exists in nature in crystalline types (such as quartz, cristobalite, chalcedony, agate, opal, etc) and non-crystalline particulate, irregular or bumpy kinds. Silica is insoluble in water and does not respond with water, but it can respond with alkali to create silicate and water. Additionally, silica also has a high melting factor, solidity, and chemical stability, which makes it commonly utilized in lots of fields.

In commercial manufacturing, silica is primarily utilized to make glass, water glass, pottery, enamel, refractory materials, airgel really felt, ferrosilicon molding sand, essential silicon, concrete, etc. Additionally, individuals also utilize silica to make the shaft surface and carcass of porcelain.

Ultrafine grinding of silica can be achieved in a variety of ways, including dry ball milling utilizing a global ball mill or damp vertical milling. Worldly round mills can be furnished with agate ball mills and grinding spheres. The completely dry sphere mill can grind the typical fragment size D50 of silica material to 3.786. In addition, damp upright grinding is one of the most efficient grinding approaches. Because silica does not react with water, wet grinding can be performed by including ultrapure water. The damp upright mill equipment “Cell Mill” is a new type of mill that integrates gravity and fluidization modern technology. The ultra-fine grinding modern technology made up of gravity and fluidization totally mixes the materials via the rotation of the mixing shaft. It collides and contacts with the medium, leading to shearing and extrusion so that the material can be efficiently ground. The median bit size D50 of the ground silica material can get to 1.422 , and some bits can get to the micro-nano degree.
