ABSTRACT High-pressure roller mills, when operated normally, run smoothly. However, beyond a transition speed uu, the mill rattles and the size reduction efleet becomes less. This critical operation is caused by the air squeezed from the particle bed as it is compacted. The back-flowing air disturbs the material introduction and excites an oscillation of the torque.
