Silica is a not natural substance and among the most essential compounds of silicon. It exists in nature in crystalline kinds (such as quartz, cristobalite, chalcedony, agate, opal, etc) and non-crystalline particle, irregular or lumpy kinds. Silica is insoluble in water and does not react with water, yet it can respond with antacids to develop silicate and water. Furthermore, silica also has a high melting point, firmness, and chemical stability, that makes it extensively made use of in lots of fields.
In industrial production, silica is mainly utilized to make glass, water glass, pottery, enamel, refractory products, airgel felt, ferrosilicon molding sand, elemental silicon, concrete, etc. On top of that, individuals also make use of silica to make the shaft surface area and carcass of porcelain.

Ultrafine grinding of silica can be attained in a variety of ways, consisting of dry sphere milling using a planetary ball mill or wet upright milling. Global sphere mills can be equipped with agate sphere mills and grinding spheres. The completely dry sphere mill can grind the median fragment dimension D50 of silica material to 3.786 um. In addition, damp upright grinding is one of the most effective grinding methods. Because silica does not react with water, wet grinding can be performed by adding ultrapure water. The damp vertical mill devices “Cell Mill” is a new kind of mill that incorporates gravity and fluidization technology. The ultra-fine grinding innovation composed of gravity and fluidization totally mixes the products with the rotation of the stirring shaft. It clashes and contacts with the tool, leading to shearing and extrusion so that the material can be effectively ground. The typical particle size D50 of the ground silica product can reach 1.422 , and some bits can reach the micro-nano level.
