摘要： PROBLEM TO BE SOLVED: To stabilize the pulverizing part of a roller mill to make self-exciting vibration hardly occur even if secular distortion thereof is encountered.
SOLUTION: In the roller mill for pulverizing raw material 1 by linking a pulverizing race 5 of a turntable 3 and pulverizing rollers 18 together, both the outer side parts at the pulverizing surface in the crossing direction of the pulverizing roller 18 are formed of hardened overlay parts 19, and the central part at the pulverizing surface of the pulverizing roller 18 is formed of parent material to make it a parent material pulverizing surface. Since the hardness (wear resistance) of material at the pulverizing surface of the pulverizing roller 18 is thus differentiated in the crossing direction, the pulverizing surface of the pulverizing roller 18 is worn and deformed so that its central part becomes hollow with time and the rolling of the pulverizing roller 18 is kept stationary, thus self-exciting vibration hardly occurs, moreover, since the recess in the central part of the pulverizing roller 18 progresses at the use period of the mill is lengthened, the longer it is used, the more hardly the self-exciting vibration occurs.

摘要翻译：要解决的问题：为了使辊磨机的粉碎部稳定，即使遇到其长期变形也难以发生自激振动。解决方案：在用于粉碎原料1的辊磨机中，通过将转盘3的粉碎座圈5和粉碎辊18连接在一起，粉碎辊18的交叉方向上的粉碎表面的外侧部分由硬化覆盖层部件19，粉碎辊18的粉碎面的中央部由母材形成，使其成为母材粉碎面。由于粉碎辊18的粉碎面的材料的硬度（耐磨耗性）因此在交叉方向上有差异，所以粉碎辊18的粉碎面磨损变形，使其中心部分随时间变得中空，粉碎辊18保持静止，因此几乎不发生自激振动，此外，由于粉碎辊18的中心部分中的凹部在轧机的使用期间进行延长，所用时间越长，几乎不发生自激振动。

摘要： PROBLEM TO BE SOLVED: To provide a pulverizing device which can foresee generation of abnormal vibration and apply vibration preventing measures before abnormal vibration is generated. SOLUTION: In the pulverizing device which is provided with a pulverizing ring 1 freely rotatably supported and pulverizing rollers 2 for pulverizing a matter to be pulverized 18 between the pulverizing ring 1 and the rollers, layer thickness of the matter to be pulverized 18 present between the pulverizing roller 2 and the pulverizing ring 1 is measured by a displacement gauge 20 provided at the pulverizing roller 2. Generation of abnormal vibration is foreseen by layer thickness or layer thickness change of the matter to be pulverized by output signals of the displacement gauge 20 and the abnormal vibration is avoided by changing at least one among roller pressurizing force added between the pulverizing roller and the pulverizing ring and rotation number of the pulverizing ring. In the pulverizing device in which the pulverizing rollers 2 are supported so as to perform pendulum motion in a radical direction of the pulverizing ring 1, pendulum displacement of the pulverizing roller is measured by the displacement gauge 20 and the generation of abnormal vibration can be foreseen by the pendulum displacement measured by the displacement gauge 20.
