Graphite spheronization system for battery production
In high-performance battery manufacturing, achieving high energy density and fast charging cycles requires precise control over graphite’s particle size distribution and sphericity. The challenge lies in optimizing these parameters while minimizing ultrafine particles that can hinder battery performance.
Enhance graphite particle sphericity and yield
The NEA|Sphere by Neuman & Esser is a comprehensive graphite spheronization system designed to improve the sphericity and size distribution of graphite particles for battery production. The system is divided into three main processes: grinding, classifying, and rounding. For grinding, the NEA|Sphere M unit utilizes high-intensity grinding tools and integrated classifiers to achieve fine particle sizes with minimal overgrinding. The NEA|Sphere S unit specializes in the complete rounding of particles in a single step, significantly increasing yield. Finally, the NEA|Sphere C classifier ensures efficient fractionation, optimizing the overall yield by effectively separating flake-shaped products. This modular approach allows for customization based on raw materials, including natural graphite and petroleum coke. The grinding, classifying, and rounding units can be combined intelligently to meet specific quality criteria and production capacities.
