1. PAINPOINT driven اوپننگ
Managing the final stage of clinker cooling is a critical bottleneck with direct consequences for plant profitability. Inefficient clinker cooler operation leads to excessive heat loss, reducing thermal recovery for your preheater and calciner systems. Unstable cooling results in clinker quality inconsistencies, causing downstream grinding inefficiencies and potential cement performance issues. Frequent maintenance interventions for grates, هائيڊولڪس, and fans create unplanned downtime, while highpressure fans drive significant electrical energy consumption. ڇا توهان في ٽين ڪلينڪر جي وڌندڙ توانائي جي قيمت کي منهن ڏئي رهيا آهيو? Is your cooler refractory and mechanical component lifespan shorter than expected? The solution lies in optimizing this essential link between the kiln and the finish mill.
2. پيداوار جو جائزو: Grate Clinker Cooler
The Grate Clinker Cooler is a critical heat recovery and conditioning machine installed directly after the rotary kiln discharge. Its primary function is to rapidly reduce clinker temperature from approximately 1200°C to below 100°C for safe handling and storage, while simultaneously recovering and supplying hot air to the kiln and calciner.
آپريشنل ڪم فلو:
1. Inlet & ورهائڻ: Redhot clinker from the kiln enters via an inlet hopper and is evenly distributed across the full width of the stationary inlet grate.
2. Grate Transport & Primary Cooling: Reciprocating grates convey the clinker bed forward. Highpressure cooling air is forced upward through the grate plates and clinker layer, providing intensive quenching.
3. گرمي جي بحالي: A significant portion of the heated cooling air is directed as secondary air to the kiln combustion zone and as tertiary air to the calciner, directly improving kiln fuel efficiency.
4. فائنل کولنگ & خارج ٿيڻ: The clinker moves through subsequent grate zones with controlled air volumes for final cooling before being discharged via a drag chain or roller crusher at the cooler outlet.
ايپليڪيشن جو دائرو & حدون:
دائرو: Designed for dryprocess cement plants with rotary kilns, suitable for capacities from 1,500 ختم ڪرڻ 12,000 ٽي پي ڊي. Effective for a wide range of raw mix compositions.
حدون: Performance is highly dependent on consistent clinker granulometry; extreme variations can lead to uneven air distribution (piping). Not designed for wet process kilns or as a standalone unit without integrated heat recovery ducting.
