The ultrasonic vibration mill-grinding process can be considered as a combination of ultrasonic vibration machining process and mill-grinding process. As shown in Fig. 1 (a), the grinding wheel's motion relative to workpiece in UVMG includes the rotation motion in its own axis and the feed motion along a helical path.
The size of the holes in the perforated plate determines the fineness of grinding of the particles. Most grains can be ground in a hammer mill. Grain for human food is ground to a 1mm particle size while animal food is ground to a 3mm particle size. Hammer mills cannot be used for wet milling. Roller mills crush the grains rather than milling
