Based in Shandong, China, the company leverages decades of industry experience to deliver high-efficiency, reliable equipment that meets the stringent requirements of modern lithium battery production lines.

Introduction to Gas-Pneumatic Conveying for Lithium-Ion Materials

Lithium-ion materials, such as lithium carbonate, lithium hydroxide, and various cathode and anode active materials, are critical components in the production of rechargeable batteries. These materials are often fine powders or granules with specific handling challenges, including dust generation, moisture sensitivity, and the need for contamination-free processing. Gas-pneumatic conveying systems offer an effective solution by transporting these materials through a closed pipeline using air or other gases, ensuring safe, efficient, and clean material transfer. The equipment from HeadPowder Engineering Co., Ltd. is engineered to address these challenges while maintaining high material integrity and system reliability.

Working Principle of the Gas-Pneumatic Conveying System

The core working principle of the gas-pneumatic conveying equipment involves the use of compressed air to create a flow of material through a pipeline. The system typically consists of a material feed hopper, a rotary airlock or feeder, a conveying pipeline, and a receiving hopper or silo. When the system is activated, compressed air is introduced into the pipeline, creating a low-pressure or high-pressure environment that draws the material from the feed hopper into the air stream. The material is then carried along the pipeline to the receiving point, where the air is separated from the material, typically through a cyclone separator or a filter system. This separation process ensures that the material is deposited in the receiving container while the air is either recycled back into the system or vented to the atmosphere. The entire process is controlled by a programmable logic controller (PLC) or a dedicated control system, which regulates the air pressure, flow rate, and material feed rate to maintain optimal conveying conditions.

Operation Process of the Equipment

The operation of the gas-pneumatic conveying equipment for lithium-ion materials follows a systematic process to ensure consistent and efficient material transfer. The process begins with the preparation of the material in the feed hopper, where the lithium-ion powder or granules are stored. The feed hopper is equipped with a level sensor to monitor the material inventory and trigger the feeder when the level drops below a set point. The rotary airlock or feeder then discharges the material into the conveying pipeline at a controlled rate, synchronized with the air flow. As the compressed air moves through the pipeline, it creates a positive pressure that propels the material forward. The conveying speed and distance are determined by the air pressure, pipeline diameter, and material characteristics. Upon reaching the receiving hopper, the air and material are separated. The cyclone separator uses centrifugal force to separate the material from the air, while the filter system captures any fine particles to prevent dust contamination. The separated material is then collected in the receiving hopper, ready for the next processing step. The control system continuously monitors key parameters such as air pressure, material flow rate, and system pressure drop, providing real-time feedback and adjustments to maintain stable operation. In case of system faults or pressure drops, the control system can automatically shut down the feeder and alert operators, ensuring safety and preventing material loss.

The robust construction and reliable control system provide consistent performance, reducing downtime and increasing overall productivity.

Applications in Lithium Battery Production

The gas-pneumatic conveying equipment is widely used in various stages of lithium battery production, including raw material handling, intermediate processing, and final product packaging. In the raw material stage, the equipment efficiently transports lithium carbonate or lithium hydroxide from storage silos to the mixing and grinding units. During the intermediate processing stage, it conveys cathode and anode active materials from mixing tanks to drying and coating equipment. In the final product stage, the equipment transfers the finished battery components to packaging lines. The consistent and clean material transfer provided by the gas-pneumatic system ensures high-quality battery production and reduces the risk of material contamination, which can affect battery performance and lifespan. The equipment's ability to handle fine powders and granules with minimal degradation makes it an ideal choice for sensitive lithium-ion materials.
