Petroleum Coke Grinding Plant in Brazil
Petroleum coke grinding plant case in Brazil. HGM ultrafine mill with hot air drying producing 200 mesh petcoke powder for cement kiln fuel. Equipment and performance data.
This case study presents a detailed account of a real-world grinding mill installation project by LIMING, including project background, equipment selection rationale, installation process, commissioning results, and ongoing operational performance. The information is based on actual project data and customer feedback, providing valuable reference for similar projects.
Project Description
A cement company in Bahia, Brazil, needed a petroleum coke grinding facility to replace coal as kiln fuel. Petcoke offers higher calorific value (8,500 kcal/kg vs 6,000 for coal) but requires fine grinding and hot air drying due to its high moisture and abrasive sulfur content.
Equipment Configuration
The HGM100L ultrafine mill was configured with a hot air furnace (using recovered kiln waste heat), specialized sulfur-resistant wear components, and an enhanced explosion-proof system. The integrated drying-grinding system reduced petcoke moisture from 8% to 0.5% while grinding to 200 mesh in a single pass.
Performance and Economics
The plant produced 6 t/h of 200 mesh petcoke powder with 6,500 kcal/kg net calorific value after moisture reduction. The switch from coal to petcoke reduced fuel costs by 35% per ton of clinker. The sulfur-resistant components (tungsten carbide rollers, ceramic-lined chamber) extended wear life from 4 months to 14 months compared to standard components.
Project Insights & Lessons Learned
This project demonstrates the importance of proper equipment selection, professional installation, and comprehensive operator training for successful grinding mill operations. Key success factors include thorough material analysis before equipment selection, adherence to installation specifications, regular preventive maintenance, and prompt response to operational issues. LIMING's comprehensive service framework addresses each of these factors, ensuring long-term equipment reliability and customer satisfaction.
