Abstracts: Sugar manufacturing Industry produce sugar from the juice of the sugarcane. Sugarcane juice is extracted from the sugarcane using roller mills. Roller mill is Mechanical equipment made by metal forming process. The material used for rolling mill is generally mild steel (MS) and rolling mill is having circumferential grooves on it for the purpose which they are intended to perform. Here ‘Chalthan Sugar Industry’ is using three high rolling mill with hydraulic load applied on it. Roller mill shell is made of cast iron with some added percentage of Manganese, Phosphorous, Sulphur and shaft is made of Forged mild steel having tensile strength 63 to 71 kg/mm2.Roller mill is fitted in the journal bearing, and during season when the roller mill is in operating condition, due to some reason the failure of roller mill is detected, by Ultrasonic Testing the failure of the roller mill is ‘Crack’. In present report an attempt has been made to do analysis of this ‘Crack’ .The study revels certain conclusion which can be the possible causes of failure of roller mill crack and here we suggested some material other than the existing material forged steel C45 and did design ,fatigue ,and ANSYS analysis to determine which material will be better to use.
