Air classifier for classifying industrial minerals
Achieve precise particle separation with advanced air classifiers, particularly essential for achieving the optimal fineness in powder production and effective dedusting of powder coatings, enhancing overall product quality and operational efficiency.

Classifies and Separates Fine Powders Efficiently
The Stratoplex ASP II from Hosokawa Alpine is an air classifier designed to deliver precise particle separation in various industries, including chemicals, pharmaceuticals, and food processing. This robust machine stands out due to its ability to produce a high yield of fine powders within the separation range of d97 = 10-150 µm while maintaining low energy consumption. Utilizing an air-flow (pneumatic) classification system, it seamlessly integrates into existing production lines, handling continuous operations with ease. It is particularly effective for fine classifications of materials like titanium dioxide, protein-enriched flour, and talc powder. The machine is available in stainless steel, ensuring compatibility and resistance against corrosion for applications sensitive to contamination. Additionally, it meets stringent industry compliance standards and offers configurations tailored to specific industrial requirements with engineering support available for customization.
