Como triturar pneus para reciclá-los?

Ao reciclar pneus, o primeiro passo é triturá-los. O processo de trituração consiste em cortar os pneus descartados em pedaços menores e mais fáceis de manusear.

What to Use to Shred Tires?

Tire shredding is usually completed using specialized recycling equipment, such as tire rotary shear shredders. Rotary shear shredders work by shearing solid waste through the movement between rotating blades.

This type of shredder usually adopts a low-speed, high-torque dual-axis or quad-axis design, which can effectively handle bulky or elastic materials such as tires, cables, etc.

During the tire shredding process, the rotary shear shredder uses its high torque and slow operation characteristics to evenly apply shear force to the tire, thereby breaking it into small pieces.

The advantage of this shredder is its targeted shredding effect, which can stably achieve a high degree of shredding, and it is easy to replace wearing parts and suitable for continuous operation.

Choose the Right Tire Shredder

Choosing the right tire shredder is the first step in shredding tires. First, determine the manufacturing material, expected capacity and output size of the tire shredder according to actual needs. This step is the basis for selecting equipment and ensures that the selected equipment can meet production needs.

Next, you need to choose the right type of shredder based on the material properties and processing requirements. For example, if you need to process large truck tires, you should choose tire shredding equipment with a larger capacity. Double-shaft shredders are suitable for efficient processing of hard or large-sized tires. Four-shaft shredders are suitable for high-efficiency, small-size crushing needs.

Choose manufacturers with many years of experience and strong technical strength, which can usually provide more mature and reliable products. At the same time, understand the equipment materials, manufacturing processes, and performance parameters provided by the manufacturer, such as shredding capacity, energy consumption, and noise level.

Tires Shredding Steps

During the shredding process, the tires first need to be sorted to remove any foreign materials that may interfere with the recycling process, such as metal wire and textile fibers. By stripping the steel wire from the waste tires using equipment such as tire bead separators, the waste steel wire can be sold as general industrial solid waste for comprehensive utilization.

Next, use a rotary shredder or other tire pre-shredding equipment to shred the tires into palm-sized pieces, which are then passed through a fine grinding crusher and further crushed into pure particles. During the multiple stages of the shredding process, magnets can be used to separate the steel wire to ensure the purity of the rubber particles.

During the shredding process, metal parts can be removed using electromagnetic separation technology. Electromagnetic separators can effectively separate steel wire from rubber particles, ensuring the quality of the final product.

For the removal of textile fibers, vibrating screens and pneumatic flow separation technologies can be used. These methods can separate textile fibers from rubber particles, resulting in purer rubber particles.

Some advanced shredding methods also include freezing tires with liquid nitrogen. At low temperatures, rubber blocks are fed into a shredder for high-speed impact crushing. Since the low temperature makes the rubber brittle, the rubber blocks are easily crushed into coarse rubber powder at this time. Most of the metal and fiber impurities have been separated at this stage.

The crushed rubber fragments can be further processed into products for different uses, such as rubber asphalt, sports track surfaces, playground ground covers, etc. In addition, these rubber fragments can also be used as raw materials for fuel or other industrial uses.
