Providing a corrosion-resistant weighing solution for a leading lithium battery manufacturer

As the green wave sweeps the globe, demand for lithium batteries has surged due to their role as key energy carriers in electric vehicles and energy storage industries. To meet the growing demand, the leading new energy company BYD planned to build a 30,000-ton battery-grade lithium carbonate project in Nanning, Guangxi. After rigorous selection processes, Minebea Intec was chosen to provide weighing systems for lithium carbonate thickeners.

Within lithium carbonate production process, thickening plays a critical role in concentration enhancement, serving as a key quality control point. Weighing process allows customers to dose additives precisely, control product quality and document material usage. Minebea Intec tailored the solution based on multiple aspects and BYD precision requirements. Four load cells PR 6212 and mounting kits PR 6012 were installed under every vessel. The collected signals were then transmitted via a junction box to the weight indicator X2, subsequently uploaded to the DCS system for automated control of the charging and discharging process.

By installing load cells, an ordinary vessel transforms into a scale. Unlike static scales, the application accuracy of vessel weighing is influenced by multiple factors. The horizontal force caused by stirring is one of the major challenges.
