Fluid Bed Dryer for Recovered Carbon Black
Efficient, continuous drying for stable rCB quality and reliable downstream processing.
Recovered carbon black from pyrolysis requires precise moisture control to prevent agglomeration and ensure consistent product performance. Ventilex fluid bed dryers provide uniform drying, high throughput, and energy-efficient operation for industrial-scale rCB production.
✔ Prevent agglomeration
✔ Improve flowability and handling
✔ Achieve consistent moisture levels
The challenge of drying recovered carbon black
Each year millions of end-of-life tires are processed through pyrolysis, producing valuable recovered carbon black (rCB). Before rCB can be reused in rubber, plastics, or pigment applications, it must be carefully dried.
However, rCB drying presents several challenges:
-
Hydrophilic particles retain moisture
-
Fine powders tend to agglomerate
-
Inconsistent drying affects downstream processing
-
High energy consumption in traditional drying systems
Without proper drying technology, product quality and handling become difficult.

The Ventilex solution for rCB drying
Ventilex fluid bed dryers are engineered to deliver uniform drying and stable product quality for recovered carbon black production.
A controlled stream of hot air fluidizes the rCB particles while the Ventilex shaking motion ensures homogeneous product movement and accurate residence time control.
This results in:
✔ Consistent moisture levels
✔ Excellent product flowability
✔ Reliable continuous operation

How the fluid bed drying process works
In a fluidized bed dryer, heated air passes through a perforated plate and fluidizes the material, causing particles to behave like a fluid. This ensures excellent mixing and highly efficient heat transfer.
The Ventilex shaking mechanism further improves product transport, ensuring:
- Homogeneous drying
- Controlled residence time
- Minimal product degradation
