The paper deals with the Design and analysis of shaft and rotor assembly for hammer mill crusher of capacity 0.1 (100kg/hr) tones per hour transmitting 20 B.H.P and a speed of 750 rpm. The design is based on the standard design procedure. In the present work by using the standard design procedure, diameter of rotor shaft of hammer mill crusher has been designed. The design should be safe when the values obtained from the present design procedure were compared with the values and results obtained from the analysis using Ansys package.
When the shaft is rotated at rated speed (rpm) and the loads applied to the shaft it should not bend during rotation. When the shaft is rotated under free conditions, deflections will be created due to the critical speed of the shaft. To compare this deflection shaft was designed such that the natural frequency and speed is under limits. In this project the shaft and rotor assembly of hammer mill crusher was modeled using Pro-e modeling package and the FEM model of the shaft was developed using Ansys package. Meshing of the shaft model was done and the loads, stresses that were applied for the shaft to be checked out that the design should be safe one.
