Design of Shredder Machine for ELV Tyres

Abstract

Waste tyres generated in India make up around 7% of the total waste tyres of the world. With the advancements in the automotive industry, the tyre industry is rapidly increasing through projected growth of 6–8%. With this development, the amount of tyre’s waste increases and the risk to the environment increases. Recycling of tyres helps to reduce the negative effects. Tyre shredding is the first step towards recycling as well as reducing the space needed by waste tyres. This study has mainly focused on detailed shredder machine design and analysis. The components of the system were modelled using 3D modelling software, and ANSYS was used for its finite element analysis (FEA). In this analysis, a couple of criteria for cost-effective shredding of scrap tyres were addressed. More emphasis was on cutting blade design. Analysis revealed that design was safe taking into account safety and strength criteria.
