摘要： A roller mill in which raw material fed between the upper surface of a pulverizing table and a pulverizing roller is pulverized by compression therebetween, wherein at least one annular recess coaxial with a roller shaft being formed on the pulverizing roller, thereby attaining reduction of self-excited vibrations of the roller mill and improvement of the pulverization efficiency. Further, in order to enhance these effects, the depth of the recess is set larger than the average grain size of the raw material. Moreover, the gap between the pulverizing table and the pulverizing roller has a wedge-like sectional shape which becomes narrower toward the outside of the pulverizing table, whereby the raw material which has been pulverized by compression between the table and the roller is prevented from escaping in the axial direction of the roller shaft, thereby attaining reduction of the self-excited vibration and improvement of the pulverization efficiency.
