1. PAINPOINT DRIVE NOLEING

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? Үйл ажиллагааны нийтлэг саад бэрхшээлүүд орно:
Excessive Heat Loss & Эрчим хүчний өндөр хэрэглээ: 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.
Засвар үйлчилгээний өндөр зогсолт & Зардал: Traditional grate plates and mechanical drives suffer from rapid wear under extreme thermal cycling, байнга болоход хүргэдэг, unplanned shutdowns for replacements and repairs.
Poor Quenching & Clinker Quality: Inadequate air distribution results in incomplete quenching ("улаан гол"), producing inferior clinker with reduced grindability, which increases grinding costs and can affect final cement strength.
Байгаль орчныг дагаж мөрдөх дарамт: Inefficient cooling can lead to higherthannecessary secondary air temperatures, impacting NOx formation and making emission control more challenging and costly.

Үйлдвэрийн менежерүүдийн гол асуулт бол: хэрхэн тогтвортой байдалд хүрэх вэ, efficient clinker cooling to stabilize kiln operation, maximize heat recovery, and reduce total cost of ownership?

2. БҮТЭЭГДЭХҮҮНИЙ ТОЙМ

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 (ихэвчлэн 100 ° C-аас бага байдаг) for conveying and storage. Үйл ажиллагааны ажлын урсгал нь орно:
1. Хяналттай хуваарилалт: Hot clinker is evenly distributed across the width of the cooler's inlet via a feed mechanism.
2. Stratified Cooling & Тээвэр: 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. Эцсийн хөргөлт & Ахах: Fully cooled clinker passes over a fine grate section for final temperature stabilization before being discharged via a drag chain or other conveyor.
5. Тоостой харьцах: Fines generated are collected via hoppers and airtight extraction systems.

Хэрэглээний хамрах хүрээ & Хувьсгал: This equipment is designed for highcapacity cement production lines (ихэвчлэн >2000 TPD). Тохиромжтой гүйцэтгэлийн хувьд клинкер гранулометрийн тогтмол шинжилгээ шаардлагатай; it is less suited for processes with extreme variations in material size or dust load without specific grate adaptations.

Үйлдвэрийн хүчин чадлыг сайжруулах сорилт

A major producer operating a 4500 TPD line was limited by an outdated cooler causing high discharge temperatures (>120°C) and frequent grate failures every 14 months.The solution involved retrofitting a new modular reciprocating grate cooler section with advanced drive controls into the existing footprint.Postimplementation field data shows discharge temperatures stabilized below +80°C.This increased mill throughput by 6%, extended grate life to forecasted26 months,and reduced specific energy consumption by4 kWh/ton of clinker ground.

Process Stability Optimization

A plant struggledwith significant kiln feed temperature fluctuations (±50°C) due topoor cooler control.This ledto inconsistent burnand higher fuel use.The implementation focused on upgradingthe cooler’s PLCwith advanced bed depth control algorithms linkedtothe new zonalair flow management system.The results demonstratedkiln feed temperature variation tightenedto ±15°C.This stabilization reducedspecific fuel consumptionby2.5%and improvedclinker C3S content uniformitybya measurable margin.
