Ultra-fine dry grinding mill for glass and ceramics
In industries requiring the ultra-fine grinding of hard, temperature-insensitive materials like glass and ceramic, achieving the necessary particle size can be energy-intensive and costly. Engineers often face the dual challenge of high energy consumption and achieving consistent particle distribution.
Achieve precise ultra-fine grinding with reduced energy demands
The PULVIS by Hosokawa Alpine is an energy-optimized vertical dry agitator bead mill designed specifically for the ultra-fine grinding of hard materials. This system features an integrated dynamic classifier for steep particle size distributions and sharp top cuts. The compact design makes it ideal for both laboratory and production scales. The milling component, located at the bottom, combines impact grinding and attrition while jets of air cool and transport particles, ensuring efficient operation. The classifier effectively separates fine products from coarser particles, which are reintroduced into the grinding zone. The PULVIS is notable for its ability to achieve particle sizes down to d97 < 1μm with up to 80% energy savings compared to traditional methods. It incorporates ceramic linings and parts for enhanced wear protection, easy maintenance, and quick material changeovers. This makes the PULVIS particularly suitable for grinding applications in the glass and ceramic industries, as well as others that require high purity and minimal contamination.
