Project Overview:
A major industrial group commissioned two new rotary kilns, each producing 600 tons of lime per day. To maximize output, reduce downtime, and ensure long-term stability, they turned to JHY Ref for a complete refractory solution.
Our Solution:
JHY Ref provided a full-package refractory supply and engineering service, tailored specifically for the customer’s high-temperature and high-wear operating environment.
Key highlights include:
High-Performance Magnesia-Spinel Bricks for the burning zone, achieving outstanding chemical resistance and minimizing thermal spalling.
Customized High-Alumina Bricks in the transition zone to optimize structural durability under varying temperatures.
Advanced Insulating Systems in the cooler and kiln hood areas to significantly reduce heat loss and improve energy efficiency.
Precision Joint Systems using high-strength mortars and flexible expansion joints for maximum lining integrity.
Performance Improvements:
| Item | Before (Conventional Materials) | After (JHY Ref Solution) | Improvement |
| Estimated Refractory Lifespan | 12–14 months | 15–18 months | +20% |
| Energy Consumption per Ton of Lime | 950–980 kcal/kg | 900–930 kcal/kg | -5% |
| Maintenance Frequency | 1 major shutdown/year | 1 minor adjustment/year | Lower maintenance cost |
| Kiln Running Stability | Moderate | Excellent | Significantly Improved |
