Classifier mill for ultra-fine grinding and precise particle size control
Achieve consistent ultra-fine particle distribution with a mill designed for high-precision grinding and classification, crucial for maintaining product quality across your applications.

Grinds and Classifies Fine Powder Efficiently
The Zirkoplex ZPS classifier mill from Hosokawa Alpine is a versatile solution tailored for fine powder processing across multiple industries. It integrates an impact beater mill with a Turboplex classifier for precise top-size limitation, ensuring high fineness values ranging from < 5 µm to 200 µm. This system excels in processing materials with a Mohs’ hardness of approximately 3.5, making it ideal for diverse applications like pharmaceuticals, food processing, and lithium-ion battery materials. Using a unique combination of an impact beater and a stationary triangular-ribbed grinding track, the Zirkoplex ZPS efficiently comminutes feed materials, while its integrated classifier ensures only the desired particle size is discharged. The design supports continuous, high-speed operations and includes special fluidisation equipment for processing sticky products. The system optimizes air flow for cool grinding, reducing energy consumption while maintaining stable classifying characteristics. The ZPS offers robust construction with welded designs and special steel grinding elements. It supports CIP for easy cleaning, essential for frequent product changes. Customization options include rotor speeds and chamber sizes, with engineering support available to tailor the equipment to specific production needs. Available in explosion-pressure-shock-proof models, it meets stringent safety standards and is compatible with various materials, enhancing its suitability for critical sectors.
