Grinding + Shaping Integrated Solution
Our grinding and shaping combination is specifically optimized for anode material production. The process integrates fine grinding, precision classification, and spheroidization in one continuous flow, ensuring both particle size control and improved roundness. Compared to using standalone equipment, our integrated solution reduces handling loss, improves yield, and enhances the electrochemical performance of graphite powders. This approach has already been validated in multiple industrial projects, helping manufacturers achieve higher tap density, stable Dv50/Dv90 control, and lower overall energy consumption.
Seamless Combination
The grinding and shaping stages are fully integrated into one continuous solution. By reducing intermediate handling and ensuring smooth material transfer, we minimize powder loss, improve system stability, and enhance overall production efficiency.
Improved Material Performance
The shaping process significantly improves particle roundness and tap density, which are critical for electrode performance. Better spheroidization leads to higher first-cycle.
Flexible Configuration
Depending on raw material characteristics (natural graphite, artificial graphite, or hard carbon) and production targets, different mills and shaping machines can be flexibly combined. This ensures every line is tailored to the customer’s unique process, capacity, and quality requirements.

Raw Material
Natural graphite anodes are made by spheroidizing, purifying, coating, and carbonizing flake graphite. Known for their cost-effectiveness, they are widely used in 3C products and are seeing growing adoption in power batteries as R&D investment increases.
Crushing
The composite crusher crushes natural graphite through high-speed centrifugal collisions and repeated internal friction. A closed-loop system with screening ensures efficient size reduction and consistent particle size.
Flotation
Flotation is a vital beneficiation process that separates graphite from impurities by exploiting differences in surface properties. With selective reagents and air bubbles, graphite particles attach to bubbles and rise to the surface, achieving efficient separation and higher purity. This ensures elevated carbon content and optimal performance for subsequent processing.
Mechanical Spheroidization
The shaping machine and ring roller mill spheroidize flake graphite, enhancing surface area, density, and electrochemical performance. A closed-loop system ensures consistent particle size through repeated collisions and precise screening.
Shaping
Shaping is the process of mechanically refining graphite particles to achieve more uniform dimensions and improve surface smoothness. This step helps optimize particle flow characteristics, prepare them for subsequent processing, and enhance overall material consistency.
Purification
Natural graphite is purified—typically to over 99.95%—by chemical, thermal, or combined methods to remove ash, metals, and other non-carbon impurities, improving electrochemical performance and stability. It is then crushed in a high-speed system where repeated collisions and a closed-loop process ensure precise and consistent particle size.
Coating & Granulation
The coating and granulation rotary kiln modifies the surface of spherical graphite by forming a uniform amorphous carbon layer. This coating repairs structural defects and shortens lithium-ion diffusion paths, enhancing initial coulombic efficiency, cycling performance, and overall electrochemical kinetics.
High Temperature Carbonization
The high-temperature carbonization rotary furnace heats pitch- or resin-coated graphite below 1200 °C to prevent solvent co-intercalation, improving rate capability and cycling stability of the anode material.
Screening, Demagnetization & Packing System
The final product handling line integrates screening, blending, demagnetization, and packaging for natural graphite. Using a sealed negative-pressure pneumatic system, it minimizes dust and contamination while ensuring efficient processing. All operations are centrally managed through a unified digital control system for remote monitoring.
Applications & Industry Cases
Our grinding, shaping, and integrated production line solutions have been widely applied in the field of anode material processing. From natural and artificial graphite to hard carbon for sodium-ion batteries, our equipment has helped manufacturers improve yield, reduce energy consumption, and achieve stable product quality. With successful projects across China, Southeast Asia, Europe, and other regions, we are trusted by both established battery material producers and emerging innovators.
