Description

Technical Ceramic classifying wheels

In the field of ultrafine powder processing, air flow classification is an important means to obtain narrow distribution and ultrafine particles. The design and manufacture of classifying wheel is the core technology of the classifier. The air classifier of German alpai enjoys a good reputation in the world, and is the designated equipment of some powder manufacturers which require strict particle size distribution. There are usually two kinds of classifying wheels: metal and ceramics. For some materials sensitive to magnetic pollution, ceramic classifying wheels must be used.
