Recently, the customized lithium hydroxide continuous carbonation and lithium precipitation system—designed by Yanming Equipment for a new energy lithium battery recycling enterprise to produce battery-grade lithium carbonate from waste lithium batteries—has completed full-scale manufacturing and was successfully shipped on November 20th. Three trucks loaded with complete sets of equipment departed for the project site. Prior to this, the supporting disc-type continuous drying system for battery-grade lithium carbonate had been installed and commissioned in advance. The precise delivery of this carbonation system marks the entry of the cooperative project into a critical implementation phase, demonstrating Yanming Equipment's strong technical capabilities and full-process service advantages in the chemical equipment sector.  

 Cutting-edge Technology Drives Efficient & Stable Solutions  

As the core equipment of the project, this lithium hydroxide continuous carbonation and lithium precipitation system for battery-grade lithium carbonate leads industry standards with multiple innovative designs, fully meeting the cooperative enterprise's requirements for high capacity, low loss, and reduced magnetic impurities. Its advanced technical design enables on-line switching processing, significantly improving operational efficiency and reducing personnel workload. Addressing the industry pain points of material scaling and pipeline blockage, the equipment's feed inlet adopts a special structural design combined with an optimized high-flow-rate scheme to fundamentally prevent scaling and blockage. The gas distribution device features an anti-clogging structure, effectively extending the pipe blockage cycle and ensuring stable continuous operation.  

In terms of core performance, the system's designed capacity meets the customer's production needs, supporting 24/7 continuous operation with an annual operating time of up to 7,200 hours. The main body of the equipment is made of 304 stainless steel with an internal polishing precision of Ra0.8, strictly complying with more than 60 national and industry standards such as TSG 21-2016 and GB150. Through precise material balance and heat exchange design, the system achieves a carbon dioxide utilization rate of 95%, ensuring product quality while prioritizing energy conservation and environmental protection. Additionally, the system is equipped with a Siemens PLC control system and intelligent monitoring instruments, enabling remote control, fault alarm, and safety interlock functions to comprehensively enhance automation levels and operational safety.  

 Full-process Premium Services Escort Efficient Project Advancement  

From technical docking to equipment delivery, Yanming Equipment has always centered on customer needs, providing full-cycle and all-round premium services. In the early stage of the project, the technical team conducted an in-depth understanding of the customer's production conditions, and tailored the equipment design plan based on the climatic characteristics and geological conditions of the project site to ensure stable system operation in complex environments. During the production process, strict factory quality inspection procedures were implemented, with each process complying with quality standards and key components undergoing multiple inspections to ensure a 100% qualified rate of delivered equipment.  

To guarantee project progress, the company efficiently coordinated production and logistics resources, organizing shipment immediately after completing equipment manufacturing, and the three trucks of equipment were accurately delivered as scheduled. Prior to this, the installation and commissioning of the drying system had been completed in advance, with technical personnel providing on-site guidance to quickly resolve various issues during installation and ensure the equipment was put into trial operation in a timely manner. Moving forward, the company will continue to provide professional installation guidance, personnel training, and commissioning services—covering key areas such as process principles, operation and maintenance, and emergency handling. It also commits to 2-hour response and 24-hour on-site arrival during the warranty period, along with long-term support for spare parts supply and technical upgrades, to fully ensure stable system operation.  

The successful shipment and delivery of this lithium hydroxide carbonation system is a dual testament to Yanming Equipment's technical strength and service quality. In the future, the company will continue to deepen its presence in the chemical equipment field, providing customized solutions for customers in new energy, environmental protection and recycling industries with more advanced technology and higher-quality services. It will help customers achieve efficient production and green development, and jointly create a new situation of win-win cooperation.
