Cement Kiln Clinker CoolerCements
The clinker cooler is a device in the cement kiln process designed to rapidly cool high-temperature clinker (1,400–1,500℃) produced in the kiln using cooling air. Its purpose is to stabilize clinker quality, recover heat, and improve mechanical conveyability.
Examples of Refractory Applications
| Part | Main Refractory Used | Properties |
|---|---|---|
| ①Cooler | High-alumina refractory material (Al₂O₃ 60–90%) | Heat resistance, thermal shock resistance, abrasion resistance |
| ②Burner Area | High-alumina refractory material (Al₂O₃ 80–90%) | Heat resistance, thermal shock resistance, abrasion resistance |
