Carbon Black Granulation Line

Carbon Black Pelletizing Line – Process Overview

1. Raw Material Feeding

   • Carbon black powder (furnace black, recovered black, or specialty black) is fed into the system.

   • Small amounts of water or binder may be added to improve pelletizing.

2. Mixing / Conditioning

   • Powder is uniformly mixed with water and/or binder.

   • Ensures consistent moisture content and prevents dust.

3. Pelletizing

   • Material is formed into pellets using a pelletizer:

     • Disc pelletizer – rotating pan creates spherical pellets.

     • Drum pelletizer – rotating drum forms pellets.

     • Roller (twin-roll) pelletizer – compresses material between rollers.

4. Drying

   • Wet pellets are dried to remove excess moisture.

   • Ensures proper hardness and storage stability.

5. Cooling

   • Hot pellets are cooled to room temperature.

   • Prevents deformation during storage or transport.

6. Screening / Classification

   • Pellets are sieved to remove fines and oversized particles.

   • Ensures uniform pellet size.

7. Packaging

   • Finished pellets are packed into bags or bulk containers.

   • Ready for shipment or automated feeding in downstream processes.

8. Dust Collection / Environmental Control

   • Dust and fine powder are collected.

   • Ensures a clean and safe working environment.

✅ Key Points:

• Moisture and binder are crucial for pellet quality.

• Pellet size and hardness can be adjusted by pelletizer type and process parameters.

• Suitable for furnace black, recovered black, and specialty carbon black.

Conventional Carbon Black Raw Materials

1. Furnace Black (Furnace Carbon Black)

Characteristics: Fine powder, good dispersibility, high blackness.

Applications:

• Tires

• Rubber products

• Plastics

• Inks

After Pelletizing: Reduces dust problems and facilitates automated feeding.

2. Pyrolytic / Recovered Carbon Black

Source: Derived from waste tire pyrolysis or waste rubber.

Characteristics: Uneven particle size distribution, high impurity content, requires modification or binder addition for pelletizing.

Applications:

• Rubber filler

• Low-end plastic modification

• Export raw material

Pelletizing Advantages: Improves transportability and increases product value.

3. Semi-Reinforcing or Conductive Carbon Black (Specialty Carbon Black)

Types: Conductive carbon black, semi-reinforcing carbon black.

Applications:

• Conductive plastics

• Cable sheaths

• Battery materials

Pelletizing Requirements: Uniform particle size and structure, prevent agglomeration, maintain conductivity.

1. Dust-Free Production

   • Converts fine carbon black powder into pellets, reducing dust pollution.

2. Improved Handling & Transport

   • Pellets are easier to store, transport, and handle than loose powder.

3. Uniform Pellet Size

   • Ensures consistent particle size for automated feeding and downstream processing.

4. Enhanced Product Value

   • Pelletizing increases commercial value, especially for recovered or specialty carbon black.

5. Adaptable to Different Carbon Black Types

   • Works with furnace black, recovered black, semi-reinforcing, or conductive carbon black.

6. Flexible Pelletizing Options

   • Can use disc, drum, or twin-roll pelletizers depending on production needs.

7. Eco-Friendly Operation

   • Includes dust collection and emission control systems for safe and clean production.

8. Energy Efficient & Low Maintenance

   • Simple mechanical design reduces energy consumption and maintenance requirements.
