For the reuse of vehicle tires, a process called crushing is presented, which allows recycling and use of different materials for use in various industrial applications. The basic design of the tire crushing system using efficient blades was considered as an alternative solution to the problem of several business sectors, which have not yet reused the material. The objective of the research pursues the design and selection of blades for the tire crushing process and manufacturing cost analysis. Therefore, typical mechanical properties of rubber in the cutting process were analyzed, and economic knife alternatives were compared for the establishment of an appropriate tire crushing process. Each of the alternatives compared differs in mechanical characteristics and nature of the material widely spread in the local environment such as ASTM-A36, SAE -1045, and SAE-S1, the first material being the most economical and recommended, as long as the design alternative is used according to the curved flank model, with maximum deformation on average of 0.0202mm. It concludes with a low manufacturing cost regardless of the design of the blade varies, in any case heat treatment must be performed. The crushing system was sized in such a way that untreated tires are treated, typical in small vehicles, because they are very numerous since there are fewer cases of retreading. The research becomes a sustainable and feasible alternative for the medium and small industry that is good at offering products based on recycled material such as rubber.
