Used tires: how to analyze the wear of cutting tools

Tire recycling combines rubber, reinforcements and components that require several preparation and separation operations. The selection of blades for tire recycling begins by identifying at what stage they work and what material they actually receive. A pre-shredding tool does not fulfill the same function as one used in subsequent reduction.

Describe the material of each stage

Record whether whole tires, pre-shredded fragments, or rubber with a certain degree of separation arrive. Include inlet dimensions, presence of steel, and external contamination. This data makes it possible to distinguish abrasive wear from damage related to impacts or out-of-specification flow. The commercial description of the waste, by itself, is not enough to define the tool.

Read the wear marks

Photograph each position with identification and a scale. A progressive rounding of the edge, a localized breakage and a contact mark require different investigations. Compare equivalent positions and entry history. Do not adjust the machine to compensate for damage without first checking the condition of supports, fixings and elements involved in cutting.

Evaluate the cost of the set

Write down useful tons between interventions, change time, possibility of recovering the edge and auxiliary parts replaced. Compare sets working with similar residuals. A lower price per blade can lose its advantage if it requires more stops or leaves unstable output quality. The relevant indicator must include the associated maintenance cost, not just the purchase.

Plan a spare test

Prepare reference and drawing, required material, mounting positions and defined wear limits for the equipment. Validate compatibility before trying an alternative replacement. Establish acceptance and withdrawal criteria with maintenance. ELDAN includes tire recycling among its applications: each line requires confirming the combination of equipment and tools according to its configuration.

Frequently asked question

Can tire steel be treated as any impurity?

No. The reinforcements are part of the waste and must be considered in the process design. The tool and separation steps must correspond to that application.
