The objective of this paper is to explain the mechanism of the occurrence of self-excited vibration observed in roller mills. In the first report, it is determined that the vibration of a roller mill is a kind of stick-slip motion, and the powder has negative-damping properties relative to velocity. We assume that these negative-damping properties cause the vibration of the mill. Thus, by this assumption, we model a three-degrees-of-freedom vibration system with such friction characteristics for a simplified test apparatus and propose the corresponding equations of motion. The fluctuations similar to the experimental results are obtained by numerical integration of them. Moreover, we note that the negative-damping properties cause the fluctuation in rotational motion of the roller.
