Centrifugal Classifier

CTC series air classifier is designed under the guidance of our German experts, and it is specially developed for separating powder products between 32-250μm. It does not require any peripheral equipment, such as cyclone collector, bag filter, induced draft fan, etc.

Working Principle

Raw material enters the classifier from the top and falls onto the rotating bulk pan. The bulk pan distributes the product in an adjustable airflow created by an internal fan. Fine particles are entrained in the airflow and carried to the outer chamber, while coarse particles fall into the inner chamber. Fine powder products and coarse powder products are discharged from the bottom of the classifier respectively. This process of internal air circulation and self-grading greatly reduces investment, production and maintenance costs. When processing high-hardness materials such as abrasives and quartz, the inlet chute and internal rotating parts can be made of high-hardness materials or lined with high hardness, depending on the situation. In addition, if it is necessary to avoid iron pollution, the interior of the classifier can be lined with alumina ceramic sheets and polyurethane.
