Used tire and rubber recycling lines

The recycling of rubber and tires is a complex process aimed at recovering waste from tires and rubber materials and addressing the challenges posed by their non-biodegradable nature and environmental impact. The methods used include pyrolysis, industrial vulcanization and mechanical processes such as shredding and granulating.

Used tire recycling / reconditioning process

1. Reconditioning: Old but structurally sound tires are retreaded using recycled rubber treads to extend their life.
2. Collection and sorting: Used tires that cannot be retreaded are collected and sorted to remove foreign materials such as metal and fiber.
3. Chopping and granulating: The tires are shredded into small pieces and then granulated to produce rubber powder up to 800 µm.
4. End uses: Recycled rubber can be used in various applications, including shredded rubber, rubberized asphalt and as an aggregate in concrete.

The rubber recycling process:

1. Energy recovery: Through pyrolysis, tires can generate gases and fuel that replace coal in industrial processes such as cement kilns and paper mills.
2. Recycle: After the foreign material is removed, the rubber from the tires is shredded into shredded rubber, which is used in products such as playground flooring, underlays for various types of flooring and rubberized asphalt for roads.

Waste tire and rubber recycling technology flow

Stage 1 - Primary Tires 

At this stage, the tires are fed into the primary shredder (item 2) via the feeding system. The shredder is a high-torque, low-speed shredder that breaks down whole tires into strips of varying sizes. The shredded strips are approximately 50 mm wide x 300 mm long, up to a maximum of 400 mm long. The strips, up to 150 mm in size, are sifted. Strips larger than 150 mm will be sent back to the primary shredder to produce rubber strips of constant size.

Stage 2 - Secondary Tires

At this stage, the rubber resulting from the primary shredding of the tires is fed into the secondary shredder (item 8) via a belt feeding system. This unit is a high-powered, medium-speed machine with a sorting system, which produces 20-30 mm sized rubber chips, called „rubber mulch”. This process removes ferrous metal from the bead and tread area and then separated by a magnetic system, providing steel-free rubber moldings in a percentage of up to 98% for further processing. The material from this stage can be marketed as high quality, low-steel Tire Derived Fuel (TDF) for a wide variety of applications.

Stage 3A - Primary granulation of shredded rubber

In the primary granulation stage, the steel-free rubber chips (rubber moldings) are fed into the granulator via the belt feed system. This process removes the 50% from the textile fibers which are then separated (item 14). The material is then routed via an outlet chute and pneumatic conveying system to either the next granulation stage for further grinding or to the automatic bag filling system where it is packed for a wide range of applications using rubber granules.

Stage 3B - Final rubber granulation

In the final granulation stage, the rubber granulated in the primary stage is fed into the secondary granulator through a feed chute system. This plant is a high-speed equipment with a sorting system, which produces rubber granules with a size of 0.8-4 mm and separates the remaining textile 50% with the help of a separator and separating table (pos. 17 and 19). Secondary magnetic separation ensures the removal of the remaining 1-2% steel wire scrap. High quality rubber granules with a purity of up to 99,9% are obtained.

Used tires and rubber recycling solutions

We offer complete and customized solutions for the efficient recycling of end-of-life tires (ELTs), turning them into raw materials that can be reused as rubber granules and powder. The modular system is designed to enable the full development of the entire process, from initial stages of chopping, refining and deferrization, and up to the final granulation of the recycled rubber.

Ensures excellent adaptability to the specific needs of each customer and recycling process. Being modular, it allows equipment to be added and configured according to the requirements and production capacity of each plant. This flexibility in design and implementation ensures maximum efficiency of the entire recycling process, optimizing the cost and time required to produce high quality recycled rubber granules.

We also offer a full range of complementary equipment to complete the rubber and scrap tire recycling line. These include efficient conveyor belts, pneumatic conveying systems for efficient material handling, dust abatement systems to maintain a safe and clean working environment, and recycled rubber storage silos for optimal material management.

By integrating these complementary pieces of equipment, we ensure that the recycling line runs smoothly and efficiently, eliminating any bottlenecks or delays in the recycling process. Ultimately, our customers benefit not only from an advanced recycling system, but also from a complete and functional infrastructure ready to meet the most demanding requirements of the rubber recycling industry.
