High-end graphite electrode materials have become a key link supporting the new energy vehicle industry chain. Behind this prosperity lies an urgent need for industrial upgrading. With the iteration of power battery energy density and fast-charging technologies, enterprises have put forward nearly harsh standards for graphite powder: the particle size needs to be precisely controlled, and batch stability and low impurity content must be ensured. The bottlenecks of traditional grinding equipment in terms of efficiency, precision and environmental protection have become increasingly prominent, which has become a key pain point restricting the high-quality development of the industry.
Zenith Customized Graphite Solution
A leading new energy materials enterprise has launched the construction of a 20,000 ton/year graphite electrode powder production line. Bearing the strategic mission of seizing the high-end market, the project, after multiple inspections and technical demonstrations, finally selected Zenith MTW European trapezium grinding mill as the core equipment to solve production bottlenecks with innovative technologies.
Processed Material: Graphite
Fineness: 200 mesh
Application: Graphite Electrode
Equipment: MTW European Trapezium Grinding Mill
As a material with low hardness and high plasticity, graphite is prone to problems such as uneven particle size and dust pollution during processing. Through on-site investigations, the technical team of Zenith customized a full-process technical scheme according to the characteristics of local flake graphite, such as its crystalline form and carbon content.
In the preliminary planning stage, the team provided a simulation scheme for the plant layout. By means of logistics simulation and intelligent equipment arrangement, it reconstructed the material flow path and carried out customized optimization for the grinding unit, finished product area and conveying system. The scheme is adapted to the customer's limited site, greatly improving the site utilization rate.
The core equipment adopted is the MTW European trapezium grinding mill. Its unique curved shovel design and advanced powder separator significantly improve grinding efficiency, while ensuring a high pass rate for 200 mesh finished products, which meets the raw material precision requirements for graphite electrode pressing.
Technical Highlights of MTW European Trapezium Grinding Mill
Technological iteration, mature and stable equipment: With nearly 40 years of experience in mill manufacturing, Zenith has undergone four generations of grinding mill upgrades, boasting leading technology and stable equipment operation.
Special grinding design for high efficiency: The curved shovel design increases the material grinding area, enhancing grinding efficiency.
Bevel gear integral transmission for reduced energy consumption: Adopting bevel gear integral transmission and non-resistance air inlet volute design, it ensures better material fluidity and lower energy consumption.
Oil lubrication for extended bearing life: Both the main shaft transmission system and fan transmission system of the equipment use oil lubrication, which has lower lubrication resistance and lower oil temperature compared with traditional grease lubrication, effectively extending bearing life.
New frequency conversion powder separator for high precision finished products: Equipped with a new hanging cage powder separator with frequency conversion control, the fineness is adjustable and controllable, meeting various specification requirements for particle size.
To meet stringent environmental protection requirements, Zenith has equipped pulse dust removal equipment to ensure no dust pollution at the production site. Meanwhile, an intelligent control cabinet and remote central control system have been introduced to realize automated operation of the production line, significantly reducing labor costs.
Zenith service system runs through the entire project life cycle, serving as a key support for the success of the cooperation. A "7×24 hours" response mechanism has been established, which collects more than 30 parameters such as equipment vibration and temperature in real time through the remote monitoring system to early warn potential faults.
"We are very pleased with this cooperation with Zenith. They have been dedicated in every aspect, from technical solutions and sales process to after-sales service," the customer spoke highly of the collaboration after the project was put into operation.
The success of this project has verified the strategic value of Zenith "technology-based enterprise and innovation-driven" philosophy. It not only solves the problem of preparing high-precision graphite powder, but also reconstructs the production standards for carbon materials with green low-carbon and digital operation and maintenance.
In the future, Zenith will continue to deepen the collaborative innovation between grinding equipment and new energy materials, helping Made in China stride forward towards high-end, intelligent and green development.
