Ultrafine grinding mill for calcium carbonate slurries
Achieve precise particle size distribution in your mineral slurries with a system designed for continuous, low-energy ultrafine grinding, ensuring optimal product quality while minimizing maintenance downtime.

Grinds and Separates Mineral and Chemical Slurries
The ANR Vertical Agitated Media Mill from Hosokawa Alpine is a wet grinding system designed to optimize the ultrafine grinding of mineral slurries. This equipment features a vertical configuration for efficient single-pass operation, employing ceramic grinding beads to produce superfine calcium carbonate and other slurry products. Ideal for continuous operation, the ANR is suitable for industries such as pharmaceuticals, chemicals, and recycling, processing a range of materials from metal powders to cocoa. The mill operates with low maintenance, utilizing a mechanically and dynamically separated milling process, and includes features such as cooling for the mill stator and low-speed agitator to ensure minimal energy consumption and extended service life. Constructed from wear-resistant materials, it provides corrosion resistance and high durability. This system is available in varying power capacities, from pilot machines to full-scale production mills. Additionally, the ANR ensures compliance with industry standards and offers customization options for specific engineering needs, making it an adaptable solution for high-quality slurry processing.
