Dry grinding mill for superfine products
Achieve high fineness in your comminution processes with this advanced dry grinding mill, ideal for producing ultrafine particles with precise classification, minimizing waste and maximizing efficiency in your production line.

Achieves Superfine Grinding and Particle Classification
The ATR Dry Grinding Mill, part of Hosokawa Alpine’s advanced powder processing solutions, excels in achieving superfine particle sizes necessary for high-quality end-products such as ceramic tiles and white pigments. It operates using a vertical agitated media milling system where a rotating agitator shaft stirs ceramic grinding beads within a water-cooled chamber, ensuring a consistent milling process ideal for mineral fillers and glazing raw materials. This mill supports a processing capacity tailored for continuous operations, seamlessly integrating into existing production lines with its PLC-controlled features. Offering options for aluminum oxide or custom wear-resistant materials, it maintains material purity by minimizing contamination. Energy efficiency is maximized through low peripheral speeds while grinding beads can be recycled back into the process. Customization options include specialized grinding bead materials and chamber linings, backed by Hosokawa Alpine’s engineering support, to meet diverse industrial needs, from chemical producers to food processing companies.
