Design of Three Roller Shafts of Sugar Mill Using Static Structural Analysis

In tropical regions, Sugar is produced from beet or Sugarcane. But all industries mostly preferred sugarcane to make sugar. The sugar industry contains Milling section, Boiler section, Juice filtration section, Purification section etc. But to increase total crushing capacity per day (TCD), the milling section takes vital role in sugar industry. The main motive of sugar industry is to extract maximum amount of juice from sugarcane. In the milling section, the processed sugarcane is fed in between three roller shaft arrangement and each roller shaft assembly contains one roller, two bearing and two pinion arrangement and different loads applied on each part roller shafts. When load between all rollers varies then there is chance to bend the roller shaft assembly, to avoid this bending we will analyze the roller shaft condition. To avoid this failure, we will analyze roller shaft conditions. While analyzing roller shaft condition, we will make modeling with the help of modeling software CATIA V5. After modeling we analyze the rollers condition, when different stress or forces applied to different sections of roller shaft with the help of Finite element methods and we can calculate the maximum shear stress and total deformation on roller shaft using ANSYS WORKBENCH software and we selecting different materials for roller shaft to analyze the variation in results. When we compare the calculated and software based results using Maximum Shear stress and Total deformation for top, feed, and discharge rollers we said the roller shafts is safe to use in sugar industry and titanium alloy is best material for this roller shafts. After this, If we modified our design by changing the measurement of small section of roller shafts where bearing in placed. This was helpful to get best design for roller shafts to avoid bending.
