1. Operational Challenges in Clinker Cooling

Inefficient clinker cooling directly impacts your plant's bottom line and operational stability. Adakah anda menguruskan isu berterusan ini?
Excessive Heat Recuperation Loss: Poor cooling efficiency wastes thermal energy, increasing specific heat consumption in the kiln by 1525 kcal/kgclinker or more, a direct and continuous fuel cost penalty.
High Secondary Air Temperature Variability: Unstable cooling leads to irregular secondary air temperatures, causing kiln flame instability, inconsistent clinker quality, and increased NOx formation.
Elevated Cooler Maintenance Costs: Traditional grate designs with high failure rates of grates, plates, and drive mechanisms result in unplanned downtime. Industry averages show 35 days of annual production loss solely for cooler maintenance.
High Electrical Energy Consumption: Inefficient fan systems and pressure drops force ID fans to work harder, consuming excess power for the cooling process itself.
Poor Clinker Quality & Grindability: Incomplete or uneven quenching can result in reduced alite (C3S) formation and poor grindability in the cement mill, increasing grinding aid use and mill power consumption.

2. Gambaran Keseluruhan Produk: Advanced Grate Clinker Cooler

Our HighEfficiency Clinker Cooler is an engineered reciprocating grate cooler system designed to maximize heat recovery and clinker quenching while minimizing operational costs. It is optimized for new plant installations or as a retrofit solution for outdated equipment.

Aliran Kerja Operasi:
1. Controlled Distribution: Hot clinker (lebih kurang. 1400°C) from the kiln is evenly distributed across the full width of the fixed inlet grate.
2. Stratified Air Quenching: Highpressure air is precisely injected through multiple controlled cooling zones, providing rapid quenching from underneath while maintaining a consistent clinker bed depth.
3. Efficient Heat Exchange & Pengangkutan: The clinker bed moves along modular grate lines while undergoing efficient countercurrent heat exchange. Recuperated air at >1000°C is directed to the kiln as secondary air.
4. Final Cooling & Pelepasan: Clinker exits the cooler at a stable, ambient temperature (+65°C above ambient), ready for conveying and storage, with excess air routed to the coal mill or dedusting system.

Skop Permohonan & Batasan:
Skop: Designed for rotary kiln cement production lines with capacities from 2000 ke 12,000+ TPD. Suitable for all major cement formulations.
Batasan: Requires consistent clinker granulometry for optimal performance. Not designed as a standalone solution for severe mechanical or chemical kiln coating issues that affect clinker size.
