Power Battery Production and Recycling Evaporation and Crystallization Solutions
Lithium Battery Cathode Material Wet Process Engineering Solutions
Hebei Leheng Energy Saving Equipment Co., Ltd. was established in 2013 and is a wholly-owned subsidiary of Zhejiang Yaguang Technology Co., Ltd. (stock abbreviation: Yaguang Shares, stock code: 603282). Yaguang Shares has over 1,200 employees, including more than 300 technical and R&D personnel.
Leheng Energy Saving is located in Dachang Chaobai River Industrial Park, Langfang City, Hebei Province, with over 600 employees, including more than 100 technical and R&D personnel. It is one of the few evaporator manufacturers in China that have mastered steam power equipment technology. The company focuses on MVR (Mechanical Vapor Re-compression) energy-saving technology and continuously optimizes and integrates upstream and downstream process equipment around the MVR evaporation and crystallization system, providing customers with more optimized, efficient, and energy-saving full-process solutions. The MVR evaporation and continuous crystallization equipment produced by Leheng are widely used in pharmaceuticals, lithium batteries, chemicals, environmental protection wastewater treatment, thermal energy recovery, pipeline pressure boosting, and other fields, and are exported to Australia, South Korea, Mexico, Chile, Argentina, Uzbekistan, Southeast Asia, and many other countries and regions.
Driven by technological innovation, Leheng constantly strives for technological peaks and has successively won numerous honors, including National High-tech Enterprise, Hebei Province "Specialized, Refined, Unique, and Innovative" Small and Medium-sized Enterprise, Hebei Province Science and Technology-based Small and Medium-sized Enterprise, and Langfang City Science and Technology Award. The company has established a provincial-level industrial enterprise R&D institution and a municipal-level high-efficiency evaporation and thermal energy recovery technology R&D center. The "Direct-drive Steam Mechanical Re-compression Evaporative Concentration Equipment" developed by the company was listed in the "National Catalogue of Major Environmental Protection Technologies and Equipment Encouraged for Development (2020 Edition)".
Product Introduction
Lithium Hydroxide Industry Chain
1. Lithium Hydroxide MVR Evaporation and Crystallization
2. Lithium Hydroxide Vacuum Continuous Cooling Crystallization
3. 20,000 mt Annual Lithium Hydroxide Production Line — Equipped with Leheng Centrifugal Steam Compressor
The process of producing lithium hydroxide from spodumene includes several systems such as mirabilite, crude lithium hydroxide, refined (battery-grade) lithium hydroxide, and impurity removal liquid. From continuous freezing crystallization of mirabilite, hot dissolution to crystallization of industrial-grade mirabilite; to evaporation concentration, cooling crystallization, and impurity removal of crude lithium hydroxide; to re-dissolution, evaporation concentration, and cooling crystallization of battery-grade lithium hydroxide, resulting in 500 μm (controllable) battery-grade lithium hydroxide crystals, our company has complete and mature design and construction experience for the entire process.
Wet Process Full Flow for Lithium Carbonate Production from Battery Recycling and Wastewater Resource Recovery
Leheng has introduced an innovative crystallization + powder full-process solution in the lithium battery industry, which can achieve a complete process package from lithium sulfate to lithium carbonate finished products and by-product recovery. This solution has been successfully applied in the lithium battery industry, shortening the process flow, improving product quality, and saving operating costs for customers.
Lithium Carbonate Solid-Liquid Separation and Powder Handling Solutions
Optimizing the lithium carbonate powder handling process with the core equipment of Yaguang's filtration, washing, and drying "trinity," where the three processes of filtration, washing, and drying are completed in the same equipment. This process solution features enclosed processing, high automation, energy efficiency, and a small footprint, helping the lithium carbonate industry reduce costs, increase efficiency, and improve product quality.
Traditional lithium carbonate precipitation powder handling processes involve centrifugation or filter press dewatering, followed by washing in a washing kettle and then entering the drying system. This process has low automation, poor working conditions, and issues with material loss in centrifuges. Yaguang Group has integrated its advantageous technical resources, using the core equipment of Yaguang's filtration, washing, and drying "trinity" to optimize the lithium carbonate powder handling process, completing the three steps of filtration, washing, and drying in the same equipment. This process solution features enclosed processing, high automation, energy efficiency, and a small footprint, helping the lithium carbonate industry reduce costs, increase efficiency, and improve product quality.
Lithium Carbonate Calcination + Powder Conveying + Crushing and Screening + Magnetic Removal and Packaging Full Process Solution
Case:
Jiangxi Jinshang Lithium Production Lithium Carbonate Project Full Process Solution
Lithium Carbonate Filtration, Washing, and Drying + Lithium Precipitation Mother Liquid MVR Evaporation and Crystallization + Lithium Carbonate Powder Conveying, Crushing, Screening, and Packaging
Since its establishment, Leheng has always adhered to the corporate spirit of "Dedication, Professionalism, Innovation, and Perseverance." In the context of China's efforts to save energy and reduce emissions and achieve carbon peak and carbon neutrality, the company will continue to uphold the entrepreneurial spirit of boldness and innovation, contributing to the progress of the energy-saving equipment industry.
