In this project, the customer from a cement plant in Colombia had been facing long-term issues in their rotary kiln system, especially in the burning zone and transition zone. The main problems included frequent refractory lining failure, severe coating instability, and premature wear caused by high thermal stress and chemical corrosion from clinker materials.
The kiln was suffering from repeated shutdowns, and the maintenance cycle was becoming shorter year by year, which significantly affected production efficiency and increased operational costs.
During our technical communication, Kerui Refractory quickly identified the root causes: inadequate material selection for high-temperature fluctuation zones and insufficient resistance to alkali and clinker attack.
Based on the working conditions, our engineering team recommended a tailored refractory solution, including:
High alumina bricks for transition zones with improved thermal shock resistance
Wear-resistant and corrosion-resistant bricks for burning zones
Optimized installation design to enhance lining stability and extend service life
After implementation, the customer’s kiln performance improved significantly. The refractory lining achieved a much longer service life, kiln shutdown frequency was greatly reduced, and overall thermal efficiency was enhanced.
The client expressed high satisfaction, noting that long-standing maintenance problems had finally been resolved through Kerui’s technical solution, bringing stable and reliable operation back to their production line.
