Milling for advanced leading edge applications present various challenges, such as micronization, avoidance of contamination, and improvement of energy efficiency. In addition to all-ceramics mills, milling systems with closed-cycle mechanisms that use inert gas, etc., and classifiers that can efficiently separate fine particles, we have engineered highly sophisticated machines and systems to create optimized particle sizes for technically advanced applications. Our technology extends to particle composition and the mechanical dry coating of fine particles which maximizes particle performance in a wide variety of applications.
