Ultrafine powder mill for coatings and pigments
Optimize your ultra-fine powder production with this precise grinding and classification system, ideal for achieving high-quality pigments and fillers with consistent particle sizes, ensuring superior performance in coatings and adhesive formulations.

Grinds and Classifies Ultra-Fine Powders
The Raymond Ultrafine Mill from Schenck Process is a state-of-the-art vertical ring-roll mill designed for ultra-fine powder processing. Utilizing a compact air-swept design with integral classification, it excels in grinding and classifying powders for diverse applications, including coatings, pigments, and catalysts. A unique feature of this mill is its ability to achieve particle sizes as fine as 50% passing 2 microns, utilizing centrifugal force to drive rolls against a grinding ring. This results in efficient ultra-fine grinding with minimal energy consumption. The mill is versatile, handling various materials such as titanium dioxide, calcium carbonate, and bioplastics, making it essential for industries including chemicals, coatings, and infrastructure. It integrates seamlessly into continuous, high-speed operations, supported by PLC-controlled automation for optimal process control and remote monitoring. Built with quality materials for durability, it offers optional configurations to enhance corrosion resistance and performance based on specific processing needs.
