Clasificadores de aire

Opposing a particle’s aerodynamic drag force with centrifugal force, air classifies create narrower size distribution and finer separations that conventional screeners. All production models utilize an adjustable forced vortex to provide uniform results while adapting to a range of feed variations. Also includes the “Mini-Split” for laboratory scale or small, batch sized separations.

Molinos clasificadores de aire

The air classifying mills combines two-staged, closed circuit grinding with internal air classification for ultra-fine micronization. The distinctive capabilities of the Prater Air Classifying Mill outperform single-stage mills when handling products that are difficult to grind or require ultra narrow particle distributions.
