Attrition Milling at Hosokawa Micron Powder SystemsDec 7, 2016 . The Mikro® UMP Attrition Mill is a high-speed cutting mill designed for the fine size reduction of plastics, waxes, and fibrous materials that do not respond well to other forms of impact milling. It is designed to grind heat-sensitive and soft materials without liquid nitrogen or conditioned air. The video.attrition milling process,How to apply an attrition mill for fine, dry grinding - Powder and Bulk .mechanical alloying. Conditions that can be varied during mill operation include the grinding media type, size, and ratio to material; material feed- rate; and grinding speed. The attrition mill's dry operation saves the process step and energy re- quired to remove waste liquid from a wet-milling chamber and eliminates.
