Finite Element Analysis Of Key Components Of Ring-Roller Mill

Along with the development of high-tech, the demand of powder materials becomes higher and higher. So powder technology developed continuously, the application of roller mill has become the development trend of grinding industries. Roller Mill not only reduced system power consumption and saved a lot of money and drying coal, but also greatly improved the production environment. The resulting economic and social benefits are very significant, and far-reaching theoretical and practical value is much higher.In the process of developing a new roller mill, we found that the influence of upper and subjacent rocker arm to roller mill properties is very large. In this paper, through UG NX3.0, a 3D solid model of upper and subjacent rocker arm of roller mill was founded. The 3D solid model was analyzed by finite element analysis in use of CAE module of UG. Through dividing the mesh, designating boundary conditions, adding payloads, specifying mesh material attributes and so on, structural analysis and parameter optimization of the intensity of upper and subjacent rocker arm was put up.The results indicated that the maximum stress of the upper rocker arm located at the linking corner of upper and subjacent parts, and subjacent part lower. The structure of subjacent part of upper rocker arm is closed box. The stress from axle hole to the corner of notch of front-end of subjacent rocker arm is larger and subjacent part lower. Through intensity checking of parts, components can meet the requirements.
