Ultrafine grinding mill for calcium carbonate slurries
In industrial applications, achieving ultrafine particle sizes in mineral slurries, such as calcium carbonate, often presents challenges. Traditional grinding methods may not provide the necessary fineness, consistency, or continuous operation required, leading to high maintenance and operational costs.
Achieve ultrafine particle sizes in continuous mode
The ANR from Hosokawa Alpine is an open-design vertical agitated media mill. It excels in the ultrafine grinding of highly concentrated limestone slurries. The mill’s design permits continuous operation with minimal maintenance. Operating in a bottom-to-top flow pattern, the feed material is ground with ceramic grinding beads, such as zirconium silicate or zirconium oxide, ensuring high whiteness and low abrasiveness. The low-speed agitator reduces energy consumption while providing durable wear rates and high service life. The mill includes a mechanical and dynamic separating element to effectively separate the grinding beads from the product suspension. Efficient cooling of the mill stator prevents overheating, and the system can scale from 45 kW pilot machines to large production mills in the MW range, making it versatile for various production needs.
Benefits
- Continuous operation reduces downtime
- Cost-effective due to low energy requirements
- High degree of product fineness and whiteness
- Low maintenance with wear-resistant materials
- Scalable from pilot to large-scale production
