MPS mill (rollerrace) model. The most significant difference between the MPS and Emill designs is the grinding mechanism. The MPS mill uses a three rollerrace system instead of the 10 ballrace system deployed in the Emill. The elutriator zone in the MPS mill also appears to be closer to the air classifier entry area.

Therefore, it is crucial to study the influence of random fluctuations on the system of cold rolling mills. In this paper, taking a model of the vertical vibration of a fourroller cold rolling mill under harmonic excitation as a prototype class for a real system, the effects of random fluctuations on the system response are analyzed.
