Tire Shredding
The challenge: managing the complexity of tire shredding
The treatment and recovery of end-of-life tires represent a crucial step for the circular economy and the efficiency of industrial processes. However, tire shredding presents significant technical challenges that require a specialized engineering approach. The strong variability between car tires, truck tires, and special applications, the presence of steel and textiles, the different input sizes, and the need to obtain a particle size consistent with subsequent stages make end-of-life tires one of the most complex applications in mechanical recycling.
Critical issues in tire shredding
Tire shredding presents specific critical issues already in the early stages of the process, because performance changes significantly based on the type of rubber to be processed and the required throughput.
Car tires and heavy-duty vehicle tires, for example, have very different behavior, structure, and resistance, with direct impacts on productivity and the choice of the most suitable technology.
As volumes or material complexity increase, it becomes essential to have high-torque systems capable of ensuring effective volume reduction, operational continuity, and resistance to strong mechanical stresses.
| Specific Challenge | Consequences of a Non-Specialized Approach |
|---|---|
| Material heterogeneity (car, truck, special tires) | Inadequate torque, unstable productivity, and chamber saturation |
| Presence of steel and structural reinforcements | Accelerated wear of blades and transmission components |
| Requirement for controlled particle size for chips or subsequent stages | Material unsuitable for screening, recirculation, and separation |
| Need for high throughput on heavy end-of-life tires | Overloads, machine stoppages, and irregular feeding |
| OTR or large-diameter applications | Need for dedicated pre-treatments, with increased plant complexity |
