Calculation of the Grading Wheel Rotor’s Critical Speed and the Analysis of its Structure Parameters

Abstract:

In a hierarchical system, grading wheel plays a very important role in material scattering and classifying. This article calculates the critical speed of the grading wheel rotor, a small part of the SZ spin flash dryer, based on finite element analysis software ANSYS. Meanwhile, in order to provide a theoretical evidence for the design of the grading wheel’s dynamic performance, analyze the influence of the bearing’s radial stiffness and some geometry parameters of the structure on the critical speed, including bearing stiffness, bearing span, cantilever length and wheel’s weigth. The result indicates that bearing span is approximately proportional to the critical speed, the cantilever length and runner quality are inversely proportional to the critical speed and the bearing span and the cantilever length have a greater impact on the critical speed.The final purpose of this paper is to find a set of proper parameters on the basis of the analysis result and optimize the rotor’s structure.
