Nowadays, screw press technology is more advanced due to a demand by oil palm industry to produce high oil production for consumer daily activity. The objective is to analyze the single and twin worm screw press by comparing several designs to maximize their lifespan of the worm screw press. This study used visual inspection, model development and simulation of worm screw press by using SolidWorks and calculation of design properties. Simulating a single tapered shaft and uniform pitch worm screw press with static and dynamic simulation resulted in the total life span yield of 4085 hours and 3621 hours, respectively. Meanwhile, simulating twin tapered shaft and uniform pitch worm screw press with static and dynamic analysis yielded the total life span of 3262 hours and 1685 hours, respectively. The option for the tapered shaft of screw press or uniform pitch was to be able to lessen the maintenance cost and further lifespan of the screw press. [ABSTRACT FROM AUTHOR]
