Silicon nitride grading wheel

In the field of ultrafine powder processing, air flow classification is an important means to obtain narrowly distributed, ultrafine particles. The design and manufacture of classifier wheels are the core technology of classifiers. There are usually two types of grading wheels: metal and ceramic. For materials sensitive to magnetic pollution, ceramic grading wheels must be used. In the current market, ceramic grading wheels are mostly made of zirconia and alumina. The newly developed silicon nitride ceramic grading wheel has better wear resistance than traditional ceramic materials, and has the unique advantages of high strength, anti-sticking and low density. Can design and produce various types of silicon nitride ceramic grading wheel products (maximum diameter up to 340mm) according to customer requirements.
