Graphite electrodes are a key industrial material, mainly produced from petroleum coke and needle coke as raw materials, combined with coal tar pitch through a complex manufacturing process. According to the differences in their performance indicators, graphite electrodes can be classified into three types: ordinary power, high power and ultra-high power.
Compared with ordinary graphite electrodes, ultra-high power graphite electrodes have a higher current-carrying capacity and higher electrolytic cell efficiency. Their high added value is in line with the direction of national supply-side reform, which prompts enterprises to optimize their production capacity structure and encourages the development of products such as ultra-high power graphite electrodes.
After extensive investigation, we chose to cooperate with Shanghai Cronus to jointly build a full-process large-scale ultra-high power graphite electrode production line. After the project was put into operation, it received unanimous praise from users, laying a solid foundation for the subsequent preparation of graphite electrodes.
This project selects high-efficiency, high-environmental protection and low-energy consumption European version grinding mills as core equipment. Professional engineers conduct on-site investigations and rationally layout the supporting facilities such as office buildings and air compressor stations to build a large-scale and high-quality grinding production line. It aims to achieve an annual production capacity of 50,000 tons of large-sized ultra-high power graphite electrodes, injecting new vitality into the local economic development.
- Processed materials: calcined coke, crushed graphite
- Finished product particle size: 200 mesh
- Finished product application: Graphite electrode
- Equipment configuration: European version grinding mill
Facing the high-standard requirements for the preparation of graphite electrode raw materials, the Shanghai Cronus European version grinding mill operates efficiently. Its special structural design is adapted to the production needs of customers. It features high grinding efficiency, adjustable and controllable fineness, and high purity of the finished product, making it a key link in the production line.
With technological iteration, the equipment has become mature and stable
The fourth-generation grinding mill has been upgraded and iterated, featuring advanced technology and stable operation.
Special grinding design ensures high grinding efficiency
The curved surface scraper design is adopted to increase the working area for material grinding and improve the grinding efficiency.
Bevel gear integral transmission reduces energy consumption
The adoption of bevel gear integral transmission and resistance-free air intake volute design ensures better material fluidity and lower energy consumption.
Thin oil lubrication extends the service life of bearings
It adopts thin oil lubrication, which has less lubrication resistance and lower oil temperature compared with the traditional grease lubrication method, and can effectively extend the service life of the bearing.
The new type of variable frequency powder separator features high precision of finished products
The new type of suspended cage-type powder separator is adopted, with frequency conversion control. The fineness is adjustable and controllable, meeting the requirements of various particle size specifications.
Production process of graphite products
It mainly includes processes such as calcination, grinding and preparation, kneading and roasting, and impregnation graphitization. Among them, the grinding stage generally involves crushing and grinding the calcined petroleum coke through a crusher and a grinding mill to obtain petroleum coke fine powder with a fineness of 200 mesh. The grinding stage is of vital importance, as the fineness distribution of the product after grinding and the purity of the finished powder will affect the quality of graphite products.
Shanghai Cronus engineers scientifically and reasonably configure the feeding system, main grinding system, classification system, fan and collection system, etc. Under the condition of meeting the specific process flow and product fineness requirements, they ensure the stable operation of the equipment during the production process and the excellent quality of the finished products, bringing extremely high economic benefits to the owner.
As an important part of the new energy and intelligent manufacturing fields, Shanghai Cronus will adhere to the concept of “innovation-driven and green development”, give full play to its own advantages, actively fulfill the core functions of a grinding equipment manufacturer, provide customers with systematic powder solutions, and jointly promote the development of the industrial chain towards a green and sustainable direction.
