Ultra-fine dry grinding mill for glass and ceramics
Achieve ultra-fine particle sizes and energy savings with a dry grinding system that integrates seamlessly into your production line, ensuring consistent quality and efficiency in processing ceramics, glass, and pigments.
Grinds and Classifies Ultrafine Materials Efficiently
The PULVIS from Hosokawa Alpine is a vertical dry agitator bead mill designed for energy-optimized ultrafine grinding. Its integrated dynamic classifier ensures precision in particle size distribution, crucial for applications in ceramics, glass, and battery materials. This system operates efficiently, achieving d97 < 1μm, with energy savings up to 80% compared to conventional methods. The working principle involves agitated media that combine impact grinding and attrition, transported by gasflow for cooling and efficient separation. Suitable for continuous production, it handles various materials including ceramics and metal oxides. The PULVIS also features ceramic lining for wear protection, easy assembly and maintenance, and customizable multi-wheel classifier heads for enhanced fineness and throughput. This unit is ideal for industries requiring rigorous particle size management, offering both scale-up from laboratory to production capabilities and compliance with industrial standards.
