Natural Graphite Processing Equipment
The composite crusher applies to the crushing process of natural graphite.Natural graphite falls vertically from the upper part ofthe machine into ahigh-speed rotating impeller, under the action ofhigh-speed centrifugalforce,it colides and crushes at hizh speed with another pat ofthe materiathat is distributed in a state around the impeller. After the materials collide with each other,they willform vortices between the impeller and theiasing and colide and rub against each other multiple times to crush them., They are discharged directly from the lower part, forming a closed loopwith multiple cycles, and controlled by screening equipment to achieve the particle size of product.
Our mechanical mill is designed specifically for anode material processing and performance improvement. It integrates multiple grinding mechanisms including impact, shear, and compression, handling feed sizes below 10 mm with high efficiency. We have equipped the system with advanced airflow channels and a state-of-the-art classifier, allowing product fineness to be flexibly adjusted within 5–75μm. With reducer-driven transmission and the material-layer grinding principle, our machine operates with low energy consumption and real-time classification to avoid over-grinding. The final powders are uniform in particle distribution and further stabilized through secondary classification via the classifier wheel and cyclone separator. Operating under micro-negative pressure, the system is safe, environmentally friendly, and easy to maintain. In addition, our intelligent control system allows automatic adjustment and smooth operation. With our targeted main machine design and optimized system control, we help you achieve precise particle size distribution and higher yields.
ZDZN TECH has independently developed high-performance ring roller mills and shaping machines, designed for the mechanical spheroidization of natural graphite.
The ring roller mill efficiently grinds flake graphite into fine powder, creating favorable conditions for the subsequent shaping process. During grinding, the powder surface is modified, enhancing specific surface area and tap density. These improvements significantly boost electrochemical performance, leading to higher first coulombic efficiency, greater reversible capacity, and excellent cycle stability in lithium-ion batteries.
ZDZN TECH has independently developed spheroidizing machines and ring roller mills, specifically designed for the mechanical spheroidization of natural graphite.
In this process, flake graphite is transformed into spherical particles while the powder surface is simultaneously modified. This significantly enhances the electrochemical performance—improving specific surface area and tap density—which leads to higher initial coulombic efficiency, greater reversible charge/discharge capacity, and excellent long-term cycle stability.
The internal combustion coated granulation rotary furnace is used for the surface modification of natural graphite. It adopts natural gas heating and preheating recovery technology to reduce energy consumption and operational costs. During the heating process, a layer of amorphous carbon is coated onto the surface of natural graphite, effectively filling defects in the graphite layers. This enhances the electrochemical performance of graphite electrode materials and makes the equipment well-suited for continuous, large-scale production.

The high-temperature carbonization rotary furnace is used for the high-temperature carbonization process of natural graphite. Inside the furnace, graphite is coated with a layer of asphalt or resin-based polymer material at temperatures below 1200 °C. This coating helps prevent the co-embedding of small organic molecules, thereby further improving the rate performance and cycling stability of the anode material.
