Prebaked anodes rank among the core raw materials for electrolytic aluminum, with steady growth in market demand. High-end eco-friendly products have become the mainstream trend of industrial development. As the largest segmented sector within the carbon materials industry, approximately 60% of global petroleum coke resources are consumed for prebaked anode production, generating an annual demand exceeding 24 million tons.
Prebaked anodes are manufactured with calcined petroleum coke and coal tar pitch as primary raw materials, supplemented by green and calcined coke scraps, through processes including calcination, grinding and baking. Grinding serves as a critical procedure determining product quality. Fine powders fill voids between particles to boost density; however, their large specific surface area consumes over 90% of the binder. Any deviation in the fineness, purity or dosage of fine powder will readily trigger unstable binder performance during kneading, leading to reduced density and mechanical strength of finished products as well as internal structural defects. Accordingly, the grinding system constitutes the primary control point for quality assurance of carbon products.
Recently, the 600,000 ton annual capacity prebaked anode project in Guangxi has been successfully put into operation. As the key equipment supplier for the calcined petroleum coke grinding section at the front end of this production line, SBM LM Vertical Roller Grinding Mill has delivered outstanding high-efficiency and stable performance, laying a solid foundation for the full-line commissioning of the project.
This project is a vital initiative to complete and strengthen the aluminum industrial chain in Southwest China, as well as a benchmark project for optimizing local industrial structure and fostering new productive forces. Upon full operation, it is expected to lift the local total prebaked anode capacity to 2 million tons, covering the production demand of around 4 million tons of electrolytic aluminum. The project will realize self-sufficiency of prebaked anodes for electrolytic aluminum production across the city, extend supply coverage to Yunnan, Guizhou and Southeast Asian markets, and help customers expand overseas market share.
As the core guarantee for stable operation and performance improvement of aluminum electrolysis, the quality of prebaked anodes is of vital importance. Adopting SBM petroleum coke vertical roller mill grinding system, the project effectively improves the uniformity and purity of finished powder fineness. All performance indicators of the system precisely match the production requirements for prebaked anodes, enabling advanced, intelligent, controllable and energy-consumption-managed anode manufacturing.
LM Vertical Roller Grinding Mill features integrated design and high efficiency with low energy consumption. It boasts a compact layout and rational structural design, equipped with an advanced PLC electric control system for a high degree of automation. The whole grinding process is managed by a microcomputer system, which can automatically generate optimal grinding solutions to save time and labor based on actual grinding conditions and reduce repeated grinding cycles. The powder produced by the equipment features uniform particle size and high purity, providing stable raw materials for prebaked anode production. Meanwhile, the equipment cuts labor input and power consumption, complying with environmentally friendly and low-carbon production standards.
Our service extends far beyond equipment delivery. SBM dispatched senior engineers to provide long-term on-site support. During equipment installation, the technical team delivered all-round technical assistance. On-site operation training and maintenance guidance were offered simultaneously throughout commissioning to ensure the customer’s workforce fully mastered maintenance skills. Thanks to rapid response and efficient execution, no-load testing and material-linked joint commissioning of the equipment were completed, accelerating the progress of official operation.
At present, the 600,000 tpy prebaked anode project in Guangxi has entered stable operation. The vertical mill production line runs continuously at full load with high efficiency. Its capacity, energy consumption and product quality indicators all exceed design standards. It serves as the core production powerhouse for the customer’s Southwest China layout and sets a benchmark reference for grinding system selection in large-scale prebaked anode projects across the industry.
Having specialized in the grinding industry for nearly four decades, SBM relies on profound technical accumulation and mature process design capabilities to deliver one-stop customized integrated solutions covering single equipment to complete full-process systems for customers.
Especially in the carbon material grinding sector, SBM has helped numerous large carbon enterprises efficiently launch prebaked anode projects adaptable to various capacity requirements. Supported by robust technology and outstanding market reputation, the company consistently stays at the forefront of the industry.
