Main use of silicon carbide: for 3-12 inch single crystal silicon, polysilicon, potassium arsenide, quartz crystal and other wire cutting. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials. Used in semiconductors, lightning rods, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic membranes, cutting tools, heating elements, nuclear fuel , jewelry, steel, protective gear, catalyst carrier and other fields. Which kind of mill equipment is used to process silicon carbide? We know that silicon carbide is a kind of deoxidizer or a very good high temperature resistant material, which is widely used in industrial production. Silicon carbide is made by using quartz sand, petroleum coke (or coal char), and wood chips as raw materials through high-temperature smelting in an electric resistance furnace. Silicon carbide is also a rare mineral in nature, Moissanite. Silicon carbide is also known as carbon silica. After being ground by a vertical roller mill, silicon carbide is used in many applications, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. At present, the raw material of silicon carbide can be supplied in large quantities, which cannot be regarded as high-tech products, and the technical content is extremely high. The application of nano-sized silicon carbide powder is unlikely to form economies of scale in a short time. (1) As an abrasive, it can be used as a grinding tool, such as grinding wheel, oil stone, grinding head, sand tile, etc. (2) As a metallurgical deoxidizer and high temperature resistant material. (3) A high-purity single crystal which can be used for manufacturing semiconductors and manufacturing silicon carbide fibers. Then, what kind of vertical grinding and grinding equipment is used for silicon carbide processing? The processing technology of raw materials directly affects the quality of silicon carbide products. Therefore, it is necessary to select suitable vertical grinding equipment in raw material processing. In general, when processing quartz sand, it is necessary to use a special high-pressure mill equipment for grinding; petroleum coke and wood chips can be processed by ultra-fine mill or ordinary Raymond mill. However, the same equipment can be used to process the three raw materials, namely the new vertical roller mill. The equipment has strong processing capability, stable performance, and the product granularity can be adjusted arbitrarily to meet different needs of users. It can be seen that when processing silicon carbide raw materials, it is a good choice to choose a vertical roller mill. The emergence of vertical roller mill has also greatly promoted the development of the silicon carbide processing industry and made an important contribution to China's industrial production.
