Fluid bed dryer for recovered carbon black

Efficient drying for a circular carbon black economy

Each year, around 1.5 billion tires reach end-of-life. Through pyrolysis, these tires are recycled into valuable materials—most notably recovered carbon black (rCB). But before rCB can be reused in applications like rubber, plastics, or pigments, it must be properly dried to ensure product consistency, flowability, and safety.

Ventilex offers a robust, energy-efficient fluid bed dryer specifically engineered for drying recovered carbon black pellets at industrial scale.

How does the Ventilex fluid bed dryer work?

Why Choose a Ventilex fluid bed dryer for rCB?

Recovered carbon black is hydrophilic, sticky, and tends to agglomerate if not dried correctly. The Ventilex fluidized bed dryer addresses these challenges with a proven drying system built for continuous operation in pyrolysis recovery lines:

  • Plug-flow drying with uniform material movement
    A controlled stream of hot air fluidizes the rCB on a perforated plate, while low-frequency, high-amplitude shaking ensures homogeneous drying.
  • Accurate residence time control
    Maintain consistent moisture levels to meet quality and handling standards.
  • Designed for industrial-scale recovery lines
    Modular and scalable to meet the demands of high-capacity operations.
  • Optimized energy consumption
    Reduce operating costs with efficient heat management and airflow control.

Typical applications for dried rCB

  • Tire and rubber manufacturing
  • Plastic compounding
  • Ink and pigment production
  • Flame retardants and composites
