5,000 TPY Petroleum Coke Ultrafine Grinding Production Line in Guangxi

Project Overview

To meet the stringent requirements of high-end industries such as lithium-ion battery anode and special graphite for ultra-fine high-purity raw materials, a carbon material high-tech enterprise in Guangxi decided to build a petroleum coke ultra-fine grinding production line. After rigorous comparison, the customer introduced the GKHGM ultra-fine ring roller mill from Guilin Mining Machinery, which can steadily produce high-end powder of 1500 mesh (D97) with power consumption of only 35 kW·h per ton of material.

Project Details

Petroleum coke material is fed into the GKHGM ultra-fine ring roller mill for grinding by the feeding system. Wear-resistant liner plates are adopted for grinding components to suit petroleum coke properties, effectively coping with the abrasiveness of petroleum coke and guaranteeing powder purity. The ground petroleum coke powder is carried by airflow into the high-precision classifier. By adjusting the classifier rotating speed, fine petroleum coke powder can be precisely controlled to steadily reach 1500 mesh (D97 ≤10μm). Unqualified coarse petroleum coke powder is separated and sent back to the grinding zone to form a closed-circuit cycle.

The cyclone collector and pulse baghouse dust collector then recover the ultra-fine petroleum coke powder, achieving an overall product collection rate of over 99.9% for the system.

Project Advantages

Specialized Design: The GKHGM ultra-fine ring roller mill is optimized for high-hardness and highly abrasive materials. Its core grinding components are fitted with special wear-resistant liner plates to ensure powder purity, paired with a turbo-type ultra-precision classifier.

High Efficiency & Energy Saving: The GKHGM ultra-fine ring roller mill consumes only 35 kW·h per ton of material, cutting energy use by more than 40% compared with traditional ball milling processes.

High Total Collection Rate: The whole system adopts a negative-pressure sealed design and is equipped with two-stage high-efficiency dust collection of cyclone and pulse baghouse. The comprehensive product collection rate exceeds 99.9% with minimal material loss.
