Application of ultrasound in comminution - ScienceDirect

2000-3-1  3.. ResultsThe ultrasonic roller mill was used to reduce the size of several substances under different operating conditions. To simulate the operating conditions in grinding plants, the system was always operated in a shock-feed state; the condition reached when the chamber formed by the two rollers is full of material, as opposed to the single particle feed state.
