M&E offers used air classifiers designed for precise particle size separation in powder processing applications across food, pharmaceutical, chemical, mineral, and industrial sectors. These systems utilize controlled airflow to separate fine and coarse particles without screens, making them ideal for applications requiring tight particle size distribution and minimal contamination. Common uses include milling circuits, ultrafine grinding, mineral processing, and powder coating operations. Air classifiers may be integrated with grinding systems or used as standalone units and often feature adjustable cut points, cyclones, and dust collection systems. Inventory commonly includes equipment from manufacturers such as Sturtevant, Hosokawa-Alpine, Mikro, STM Micron, Prater, NETZSCH, Ecutec, Bradley Pulverizer, Raymond, Schenck Process, Metso, FLSmidth, British Rema, and other leading OEMs. These systems are well suited for processing minerals, pigments, chemicals, food powders, and other dry bulk materials requiring accurate classification and separation.
