Coal Powder Production Line in Malaysia
Pulverized coal production line case in Malaysia. Ball mill and vertical mill configuration for power plant coal grinding. Equipment selection and operational 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 plant in Sarawak, Malaysia, required a pulverized coal production line to fuel their kiln. The specification called for 200 mesh pulverized coal at 30 t/h, with a hot air drying system to handle coal moisture up to 15%.
Mill Selection and Configuration
A LUM vertical roller mill was selected over a traditional ball mill for its superior energy efficiency. The vertical mill integrates grinding, drying, and classification in a single unit, reducing the equipment footprint by 60%. Hot air from the kiln exhaust was routed through the mill for energy-efficient drying.
Operational Performance
The LUM mill achieved 32 t/h at 200 mesh with 70% passing 75 microns. Coal moisture was reduced from 12% to 1.5% in a single pass. The integrated explosion-proof system, including oxygen monitoring and inert gas injection, ensured safe operation. Energy consumption was 14 kWh per ton, compared to 22 kWh for the previous ball mill.
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.
