1. PAINPOINT driven اوپننگ
Managing the final stage of cement production presents distinct and costly challenges. Are you facing persistent issues with clinker cooler efficiency that directly impact your plant's bottom line? عام آپريشنل رڪاوٽون شامل آهن:
Excessive Heat Loss & اعلي توانائي واپرائڻ: Inefficient cooling forces downstream equipment, like mills, to handle hotter material, increasing power draw and wasting recoverable thermal energy for power generation.
Unstable Kiln Feed Temperature: Fluctuating clinker discharge temperatures from the cooler create process instability in the kiln, compromising burn quality and increasing specific heat consumption.
اعلي سار سنڀال Downtime & خرچ: Traditional grate plates and mechanical drives suffer from rapid wear under extreme thermal cycling, بار بار جي اڳواڻي, unplanned shutdowns for replacements and repairs.
Poor Quenching & Clinker Quality: Inadequate air distribution results in incomplete quenching ("لال ندي"), producing inferior clinker with reduced grindability, which increases grinding costs and can affect final cement strength.
ماحولياتي تعميل دٻاء: Inefficient cooling can lead to higherthannecessary secondary air temperatures, impacting NOx formation and making emission control more challenging and costly.

2. پيداوار جو جائزو
The reciprocating grate cooler is a critical piece of finish grinding equipment in modern cement plants. Engineered for highvolume thermal exchange, its primary function is to rapidly reduce the temperature of incandescent clinker (approximately 1400°C) discharged from the rotary kiln to a manageable temperature (typically below 100°C) for conveying and storage. آپريشنل ڪم فلو شامل آهي:
1. ڪنٽرول ٿيل تقسيم: Hot clinker is evenly distributed across the width of the cooler's inlet via a feed mechanism.
2. Stratified کولنگ & ٽرانسپورٽ: Reciprocating grates move the clinker bed toward the discharge end while controlled volumes of ambient air are forced upward through the material layer.
3. Staged Air Management: Cooling air is supplied through multiple fan chambers along the cooler's length, allowing for optimized heat recovery (hot air to kiln/precalciner) and efficient quenching.
4. فائنل کولنگ & خارج ٿيڻ: Fully cooled clinker passes over a fine grate section for final temperature stabilization before being discharged via a drag chain or other conveyor.
5. مٽي سنڀالڻ: Fines generated are collected via hoppers and airtight extraction systems.
ايپليڪيشن جو دائرو & حدون: This equipment is designed for highcapacity cement production lines (عام طور تي >2000 ٽي پي ڊي). Optimal performance requires consistent clinker granulometry; it is less suited for processes with extreme variations in material size or dust load without specific grate adaptations.
