Pyrolysis carbon black is fine, dusty and hard to handle, meter and ship. This article explains how double-roller dry granulation turns it into stable granules at low energy, with screening recycle and packing as part of one dust-controlled line.
Event background
Carbon black granulation is a special-material line rather than a general fertilizer line. Binder, moisture conditioning, granulation, screening and dust control must be designed together, otherwise fines escape at transfer points and product consistency suffers.
Key facts
- Metering and dosing start at storage, with dust control at every transfer point.
- A mixer conditions the feedstock and binder for consistent granule quality.
- Double-roller dry extrusion forms granules with low energy demand and suits low-moisture feedstock.
- A rotary screener classifies product, and off-size material returns to the circuit.
- Automatic bagging or ton-bag packing completes the line.
- The route supports pyrolysis carbon black from the YOTO Group environmental portfolio.
- Process parameters are confirmed through incoming-material trials rather than assumed.
What this means for customers
The buyer converts loose, dusty carbon black into size-stable, low-dust granules that are easier to transport, meter and sell, while reducing powder loss.
How we support this
YUSHUNXIN provides the carbon black granulation line on the group's pyrolysis and environmental portfolio, with process parameters confirmed by feedstock trials.
Next steps
Provide carbon black source, ash/sulfur/pH/particle size, target granule size and capacity. We will run incoming-material trials before finalizing the configuration.
