In the field of advanced graphite processing, selecting the appropriate grinding equipment is critical to the application performance of the final product in high-tech industries such as lithium battery anode materials, sealing materials, and conductive coatings. Considering graphite's fragile layered structure, high purity requirements, temperature sensitivity (preventing oxidation from excessive heating), and strict particle size distribution specifications, vertical mills (roller mills) and jet mills (particularly fluidized bed jet mills) are currently recognized as the most ideal and mainstream equipment choices in the industry. They offer significant comprehensive advantages over traditional equipment like Raymond mills.
Vertical Grinding Mill: The Choice for Large-Scale Production and Energy Efficiency
For large-scale production of medium-fineness graphite powder (e.g., D97=45-150 microns), the vertical grinding mill is the preferred solution.
Significant Energy Efficiency Advantages: Employing the fluidized bed grinding principle, these mills crush material layers on grinding discs using hydraulically pressurized rollers, achieving extremely high crushing efficiency. Energy consumption is 30%-50% lower than traditional ball mills, substantially reducing system power usage.
Easy Particle Size Control: Integrated dynamic classifiers enable real-time adjustment of product fineness by modifying rotational speed, resulting in concentrated and stable particle size distribution.
Stable operation with environmental benefits: The fully enclosed negative-pressure system minimizes dust leakage, maintaining a clean working environment. Its robust drying capability also allows simultaneous processing of materials with slightly higher moisture content.
Relatively low maintenance costs: Wear parts (rollers, grinding disc liners) can be replaced directly online after wear, ensuring convenient maintenance and suitability for continuous, large-scale industrial production.
