The drying and calcination of lithium battery materials are critical processes that determine material quality and production line energy consumption. As global lithium battery production capacity accelerates its deployment both domestically and internationally, the market demand for stable, energy-efficient, and intelligent thermal processing equipment continues to rise. Shandong Huayi Engineering Technology Co., Ltd. will attend the CLNB 2026 Asia Battery Materials Cooperation Forum to discuss lithium battery material thermal processing equipment technology and project cooperation opportunities with partners across the Asia-Pacific industry chain.

1: Deepening Practical Experience in Lithium Battery Heat Treatment  

Shandong Huayi Engineering Technology Co., Ltd. is a high-tech enterprise integrating the design, research and development, manufacturing, and service of drying and roasting equipment. It is a privately held joint-stock enterprise with listed company investment, specializing in the development and application of intelligent systems for various drying and roasting processes.  

The company brings together an expert team with decades of experience in the drying and roasting field, accumulating extensive on-site engineering experience. In the new energy sector, it has provided intelligent drying and roasting systems for nearly one hundred enterprises, including South Korea's Sunri, Geely Group, GAC Group, China Minmetals Group, GEM, Guanghua Technology, Wanhua Chemical, Shengtun Mining, Sunwoda, Guangdong Jinsheng, Hunan Yunneng, Bambu, Zhongwei, Zhiyuan Lithium, Yingda Lithium, Zhizun Lithium, Tianqi Lithium, and Hanrui Cobalt. Its business covers the entire country, and its products are exported to overseas markets such as South Korea, Japan, Indonesia, Poland, and Hungary.

2: Comprehensive Solutions Covering the Entire Heat Treatment Process

Huayi Engineering deploys five core process technologies, covering the entire chain of lithium battery material production and recycling:

Lithium Iron Phosphate Rotary Kiln Roasting Technology

Integrating high-speed centrifugal spray drying and an oxygen-free sintering furnace, it precisely controls material particle size and moisture content, complemented by waste heat recovery, pulse dust removal, and safety interlock systems. This ensures the quality of lithium iron phosphate cathode materials while achieving energy-efficient and low-carbon production.

The fourth-generation sealing mechanism and 3.0 plate-copy design substantially increase the heat exchange area, significantly improving thermal efficiency. The equipment is highly adaptable to different site conditions, occupies a small footprint, can flexibly match various production line layouts, and demonstrates strong adaptability to multi-category processes.

Lithium Battery Recycling Technology

Complete production lines for waste lithium batteries, covering equipment design and manufacturing, installation and commissioning, and full-cycle services; integrating sealed feeding, specialized shredding, pyrolysis, and sorting units, relying on nitrogen sealing and multi-layer labyrinth sealing to ensure safe operation, with copper and aluminum sorting purity reaching over 98%.

Lithium Battery Black Powder Carbonization and Reduction Technology

Utilizing a carbothermal reduction process in a high-temperature inert atmosphere, high-value metals are directly recovered. The process is short, with low investment and operating costs, and compared to hydrometallurgy, it reduces the use of strong acids, highlighting its environmental friendliness.

Flash Drying and Roasting-Cooling Integrated Technology

Fully recovers the residual heat from high-temperature flue gas of the roasting kiln to supply flash drying, with stepwise utilization of heat, effectively reducing the energy consumption of the entire production line.

Integrated Technology for Compound Fluidized Bed Drying and Cooling

The built-in heat exchange structure enhances heat transfer efficiency, reduces exhaust emissions, and minimizes footprint. Through specialized designs for feeding, mixing, discharging, and composite air distribution panels, it addresses material agglomeration and dead bed issues, ensuring continuous operation of the production line.

The company holds more than 80 national patents; it has passed the ISO quality/environment/occupational health and safety management triple system certifications, as well as after-sales service system certification; its products have obtained EU CE certification and have been recognized as national energy-saving and carbon-reduction demonstration technology products.

The enterprise has been awarded numerous honors, including National High-Tech Enterprise, Provincial Specialized and Innovative Enterprise, Provincial Innovation and R&D Center, Green Intelligent Factory, First-Level Supplier of Global Lithium Battery Core Equipment, and Qualified Supplier in the Sinopec Industry. For many years, it has focused on addressing actual production challenges of customers, delivering competitive drying engineering solutions, and continuously creating value for customers.

3. Based on overseas expansion, exploring the path for equipment deployment.

Overseas lithium and sodium battery material projects are being concentratedly implemented, and the localized adaptation of complete drying and roasting equipment, as well as energy saving and cost reduction, have become practical demands of the industry. Equipment companies with mature experience in delivering overseas projects have become an important support for the construction of overseas production lines.  

Relying on extensive experience in implementing projects both domestically and abroad, Huayi Engineering made its debut at the CLNB 2026 Asia Battery Materials Cooperation Forum, looking forward to discussing with industry partners in the Asia-Pacific region the technological iteration and project implementation of lithium battery material heat treatment equipment.4: Seoul Sets the Stage for Precise Linking of Asia-Pacific Industrial Resources

This is not only an industry forum but also an efficient and pragmatic platform for cross-border cooperation. The conference features four sub-forums: the development of cutting-edge battery materials technology, lithium iron phosphate material technology and cooperation, the battery raw materials value chain, and new energy application scenarios and demand prospects. In addition, a 1-on-1 meeting scheduling system is provided to help participating companies directly connect with potential partners.  

Leading global battery industry companies, including LG Energy Solution, Samsung SDI, SK On, POSCO Holdings, Ecopro, Umicore, L&F, Zhongwei Co., Xiaoxing Heavy Industry, and SungEel HiTech, have all confirmed their attendance.As a technology-oriented company deeply engaged in lithium battery material drying and roasting equipment, Huayi Engineering looks forward to using this exhibition to gain an in-depth understanding of the genuine pain points and performance demands of domestic and international customers in the drying and roasting processes, thereby promoting the pragmatic transformation from technical solution exchanges to project implementation and cooperation.
