How to Convert Carbon from Tyre Pyrolysis into Carbon Black for Tyre Industry

Tyre pyrolysis is a process that converts waste tyres into useful products like oil, gas, and carbon black. This process is not only environmentally friendly but also helps in managing the waste tyres that otherwise pose a significant environmental hazard. One of the key outputs of tyre pyrolysis is carbon black, a material extensively used in the tyre industry. This article outlines the process of converting carbon from tyre pyrolysis into high-quality carbon black suitable for the tyre industry.

Understanding Tyre Pyrolysis

Tyre pyrolysis involves heating shredded tyres in an oxygen-free environment, causing the rubber to decompose into oil, gas, and solid residues, primarily carbon black and steel. The temperature typically ranges between 300°C to 700°C. The carbon black obtained from this process, often referred to as pyrolytic carbon black, needs further processing to meet the quality standards required by the tyre industry.

Processing Pyrolytic Carbon Black

The pyrolytic carbon black obtained directly from the pyrolysis process is not suitable for immediate use in the tyre industry due to its high ash content and larger particle size. Therefore, it needs to be processed to improve its properties. The following steps are involved in this processing:

  1. Grinding: The raw carbon black is first ground to reduce its particle size. This is a critical step as the particle size of carbon black affects the performance characteristics of the final tyre product.
  2. Screening: The ground carbon black is then screened to separate fine particles from larger ones.
  3. Purification: The carbon black is purified to remove impurities, including ash and other contaminants. This can be done through various methods such as acid washing or thermal treatment.
  4. Pelletizing: The purified carbon black is then pelletized to improve its handling and dispersion properties in the rubber mix.
Recommended Equipment: SCM Ultrafine Mill

For the grinding process, we recommend the use of the SCM Ultrafine Mill. This mill is designed with advanced technology to provide a fine and consistent particle size, making it ideal for processing pyrolytic carbon black.

Key Features of SCM Ultrafine Mill
  • Input Size: 0-20 mm
  • Capacity: 0.5-25TPH
  • Output Size: 325-3250 mesh
  • Developed with advanced Swedish manufacturing technology
  • Combines Chinese and Swedish technologies

The SCM Ultrafine Mill ensures that the carbon black is ground to the required fine particle size, enhancing its properties and making it suitable for use in high-quality tyre manufacturing. Its high efficiency and precision make it a valuable addition to the carbon black processing line.

Benefits of Using Processed Carbon Black in Tyres

Processed carbon black enhances the performance of tyres by improving their strength, durability, and resistance to wear and tear. It also contributes to the reduction of rolling resistance, leading to better fuel efficiency for vehicles. By converting waste tyres into high-quality carbon black, the tyre industry can benefit from sustainable and cost-effective raw materials while contributing to environmental conservation.

In conclusion, converting carbon from tyre pyrolysis into carbon black suitable for the tyre industry involves several processing steps, including grinding, screening, purification, and pelletizing. Using advanced equipment like the SCM Ultrafine Mill can significantly enhance the quality of the final product, ensuring it meets the stringent requirements of the tyre industry.
