Enhancing Efficiency In Nickel Ore Processing Through Redesigned Crusher Teeth

Abstract

This study aims to evaluate and improve the design of crusher teeth on the Mineral Sizer Crusher used in the nickel ore processing operations at PT X. The primary issue identified was the discrepancy between the actual production capacity and the initial machine design specification, where the production capacity, initially targeted at 500 tons/hour, only achieved 120 tons/hour. Additionally, frequent machine shutdowns occurred due to material accumulation that could not be efficiently crushed. This research involves analyzing the initial design, evaluating the material used, and developing an optimized crusher teeth design using SCMnH11, a material known for its high resistance to impact and abrasion. The results indicate that the redesigned crusher teeth, with optimized geometry and material properties, successfully increased production capacity to 500–550 tons/hour and reduced the risk of machine stoppages caused by material blockages. This study concludes that optimizing the crusher teeth design and selecting appropriate materials can significantly enhance the operational efficiency and reliability of the machine in nickel ore processing.
