Air Jet Mill for Electronic Battery Materials | Lithium Powder Processing Equipment
The new energy lithium battery industry continues to expand, and the powder processing technology for battery materials has become a key segment affecting cell manufacturing. Lithium battery cathode and anode materials, energy storage raw materials and other substances have specific requirements for powder purity, particle size and material activity. Conventional grinding equipment tends to cause issues such as metallic impurities, excessive material temperature rise and powder agglomeration during processing, which impair the performance of battery materials. Ordinary grinding equipment lacks sufficient structural adaptability and struggles to meet standardized mass production requirements for lithium battery materials. The air jet mill dedicated to electronic battery materials is custom-developed for lithium powder processing conditions. It is suitable for ultra-fine grinding and de-agglomeration of various electronic battery raw materials, serving as core supporting equipment for new energy powder production lines.
This dedicated air jet mill operates on the principle of pure gas impact grinding. No grinding media is involved during operation; particle size reduction is achieved through high-speed collision of materials. This fundamentally avoids impurity contamination caused by media wear. The equipment chamber, flow path components and classifier wheel adopt full ceramic protection structures made of high-purity alumina and zirconia. This minimizes metallic contamination during processing, meets the production standards for battery-grade high-purity powder, and satisfies the processing requirements of sensitive lithium raw materials including ternary materials, lithium iron phosphate and graphite anodes.
Equipped with a low-temperature grinding system, the equipment leverages the endothermic effect of gas expansion to maintain a low-temperature environment inside the grinding chamber. It limits temperature increases during material processing and prevents thermal decomposition and oxidative deterioration of lithium battery materials, fully preserving their original electrochemical activity. It is suitable for grinding heat-sensitive materials such as silicon-based materials and new energy storage materials. The entire processing workflow does not damage the microscopic structure of materials and ensures stable physical and chemical properties of finished powder.
A dynamic classification structure is built inside the equipment. The powder particle size of the final product can be flexibly adjusted by changing the classifier rotation speed to match powder specifications required for different battery cells. It effectively breaks up agglomerated particles in raw powder, optimizes particle size distribution and reduces residual coarse particles, improving the uniformity of finished powder. The equipment enables integrated continuous feeding, grinding, classification and discharging with tightly connected processes. It accommodates the large-scale, continuous mass production rhythm of lithium battery manufacturers and boosts overall powder processing efficiency.
For highly active and oxidizable battery materials, the equipment can be fitted with an inert gas protection system to create a sealed oxygen-free processing environment. It isolates materials from ambient air and moisture to prevent oxidation and moisture absorption, supporting the production of new lithium and sodium battery materials. The whole machine adopts a sealed processing structure with zero dust leakage during operation. It improves the workshop working environment, complies with clean production control standards of the new energy industry and reduces material loss and workshop contamination.
The energy consumption system of the equipment is optimized with well-designed gas flow distribution, delivering higher energy utilization than traditional general-purpose air jet mills. It cuts energy costs during long-duration mass production. Featuring a modular body design, the machine allows convenient disassembly, cleaning and maintenance. There are no dead zones inside the chamber, enabling operators to rapidly clean the chamber and switch materials to prevent cross-contamination between batches. This supports alternating production of different types of battery materials.
The air jet mill for electronic battery materials manufactured by our factory undergoes multi-condition commissioning before delivery. Indicators including grinding particle size, material purity and operational stability are verified to guarantee reliable on-site performance. The machine is applicable to processing lithium cathode and anode materials, battery powder raw materials and new energy storage materials. It can connect with small and medium pilot production lines as well as large automated mass production lines to meet different scenarios including R&D sampling and mass manufacturing for new energy enterprises.
As purpose-built equipment for lithium powder processing, this air jet mill addresses the core demands of battery material production and overcomes many drawbacks of traditional grinding equipment in high-purity, low-temperature and anti-oxidation processing. It provides stable and reliable equipment support for new energy battery powder manufacturing and aligns with the current development trend of the lithium battery industry.
