0-0.2mm Graphite Electrode Powder

Production Process

A strict quality control system and a standardized, closed-loop production model are used in the manufacturing of this product, guaranteeing constant batch quality and stable particle size. The following is the specific production process:

• Step 1: Pre-treatment and Raw Material Selection

While polluted, deteriorated, or inferior materials are thrown away, high-quality graphite electrode waste and processing offcuts are chosen as raw materials. To ensure product purity at the source, raw materials are thoroughly cleaned to get rid of surface dust, iron impurities, and other external pollutants.

• Step 2: Coarse screening and primary crushing

Bulk graphite is converted into homogenous, smaller particles by feeding qualified raw materials into specialized crushing machinery for primary size reduction. In order to prepare the material for the ensuing ultra-fine grinding, coarse screening eliminates large particles and leftover contaminants.

• Step 3: Precision Classification and Ultra-fine Grinding

Using specialist equipment, the material is subjected to ultra-fine grinding along with precise categorization. A concentrated particle size distribution devoid of large particles is produced by tightly regulating particle size ranges to guarantee that all particles fall within the 0–0.2 mm range.

• Step 4: High-Temperature Stabilization and Purification

Hazardous contaminants and trace ash are eliminated by physical purification procedures. By removing moisture and any remaining volatile elements, low-temperature drying and high-temperature stabilization techniques raise the fixed carbon content and improve structural stability.

• Step 5: Iron Removal and Magnetic Separation

Iron contaminants produced during mechanical processing are entirely eliminated by passing the pulverized powder through high-intensity magnetic separation apparatus. This completely improves powder fineness and purity by preventing contaminants from impacting electrical conductivity and performance.

• Step 6: Batch Sampling and Online Monitoring

For real-time live monitoring of important indicators such particle size distribution, carbon content, and sulfur content, laser particle size analyzers and carbon-sulfur analyzers are utilized. Every batch is subjected to thorough sample checks to make sure all parameters satisfy standard criteria.

• Step 7: Temperature-controlled storage and sealed packaging

To stop moisture absorption and secondary contamination, finished goods that pass inspection are sealed in dust-proof and moisture-proof packaging. To guarantee constant quality during storage and transit, finished goods are kept in dry, well-ventilated, temperature-controlled facilities.

Product Advantages

The powder's concentrated particle size distribution, lack of coarse particle contamination, and exceptional flowability make it ideal for precision industrial batching, coating applications, and other fine manufacturing processes. It also strictly complies with the 0–0.2mm full-pass particle size standard.

Extremely low levels of impurities and high purity: With a fixed carbon content of over 99% and very low levels of sulfur, ash, and moisture, impurity-related problems in downstream goods are successfully prevented, and the end product's stability and service life are greatly increased.

Superior thermal and electrical conductivity: preserves the fundamental high-conductivity and high-thermal-conductivity characteristics of synthetic graphite; the powder spreads uniformly to quickly create continuous conductive and thermal networks, greatly improving composite materials' electrical and thermal performance.

Strong chemical stability and high-temperature resistance: ** Does not break down or deteriorate in high-temperature environments; provides outstanding resistance to oxidation and acid/alkali corrosion, maintaining stable performance under harsh conditions and guaranteeing durability across a wide range of applications.

Eco-friendliness and a high cost-performance ratio: It is made by deeply processing discarded graphite electrode raw materials, allowing for resource recycling with minimal energy use and no emissions of pollutants. It is comparable in performance to graphite powders derived from petroleum coke, but it is significantly more affordable.

End-to-End Quality Inspection and Control

• Comprehensive Inspection of Incoming Raw Materials

Every bag of incoming raw material undergoes inspection. Key indicators-such as fixed carbon, sulfur content, ash content, volatile matter, and particle size-are analyzed individually. This process prevents substandard materials from entering storage, ensures consistent raw material quality at the source, and eliminates the risk of inferior materials compromising the performance of the finished product.

• Segmented Spot Checks During Production

Multiple inspection checkpoints are established along the production line, with random sampling and analysis conducted at standardized intervals. Covering processes such as crushing, screening, and packaging, this system monitors fluctuations in product metrics in real time. Should test data deviate from standard parameters, production processes are immediately adjusted to ensure uniformity across the batch

• Final Pre-Shipment Inspection

A comprehensive final inspection is performed before finished products are packaged and shipped, and a corresponding quality inspection report is issued; products are released from the warehouse only after meeting all parameter standards. Retained samples are kept on file to facilitate future traceability and verification, ensuring that quality records are available for every shipment.
