In lithium-ion battery manufacturing, the handling of low-temperature pre-carbonized anode materials directly affects product consistency, operational stability, and overall production costs. Designing a suitable pneumatic conveying system is therefore a critical engineering challenge.
Why Pre-Carbonized Anode Materials Are Difficult to Convey
Pre-carbonized anode materials are highly sensitive during handling due to their physical properties and processing requirements. Manufacturers commonly face issues such as:
- Material contamination caused by open or poorly sealed conveying systems
- Segregation and residue buildup during long-distance transport
- Production interruptions caused by unstable multi-stage material transfer
These challenges increase both quality risks and operating costs.

Key Design Considerations for Pneumatic Conveying Systems
When designing a pneumatic conveying system for pre-carbonized anode materials, several factors must be carefully evaluated:
- Conveying distance and routing complexity
- Material sensitivity to velocity and pressure
- Cleanliness and dust control requirements
- Energy efficiency and system automation level
A single conveying method often cannot meet all these requirements simultaneously.
Hybrid Conveying Architecture: A Practical Approach
A hybrid system that combines positive-pressure dilute-phase conveying and negative-pressure vacuum conveying offers a balanced solution.
In a real production application:
- Positive-pressure dilute phase conveying achieved distances up to 180 meters with a capacity of 4 tons per hour
- Low-velocity operation ensured stable material flow without segregation or residue
- Vacuum conveying enabled fully enclosed feeding and big bag unloading, eliminating dust leakage
This combination supports both long-distance transfer and clean material handling.

The Role of Intelligent Control Systems
Modern pneumatic conveying systems increasingly rely on centralized control platforms to improve operational efficiency.
Key capabilities include:
- Real-time inventory monitoring
- Energy consumption analysis
- Remote access via PC and mobile devices
These features enable manufacturers to optimize production scheduling and reduce long-term operating costs.
