H1: Optimize Clinker Cooling and Heat Recovery with Advanced Grate Coolers
PAINPOINT DRIVE NOLEING
Managing the clinker cooling process presents persistent challenges that directly impact your plant’s bottom line. Inefficient cooling leads to excessive heat loss, reducing the quality of secondary heat available for kiln and raw mill operations. Unstable grate bed conditions cause erratic clinker bed permeability, resulting in highpressure fans working harder and spiking energy consumption. Perhaps most critically, unreliable equipment and frequent maintenance interventions on traditional coolers lead to unplanned downtime, disrupting the entire production chain and incurring significant costs in lost output and emergency repairs.
Та нэг тонн чулуунцарт ногдох эрчим хүчний зардал нэмэгдэж байна уу?? Is your maintenance team constantly addressing grate plate wear or fan issues? Are you struggling to achieve consistent clinker quality due to uneven quenching? The solution lies in a fundamental reengineering of the clinker cooling process.
БҮТЭЭГДЭХҮҮНИЙ ТОЙМ: Advanced Reciprocating Grate Coolers
The modern reciprocating grate cooler is engineered for precise thermal management and mechanical reliability in cement production. This equipment receives incandescent clinker from the rotary kiln discharge and systematically reduces its temperature from approximately 1400°C to an ambient temperature suitable for conveying and storage, while simultaneously recovering highgrade heat for process efficiency.
Үйл ажиллагааны ажлын урсгал:
1. Хяналттай хуваарилалт: Hot clinker is evenly distributed across the full width of the grate via a regulated feed system.
2. Stratified Cooling: Reciprocating grates transport the clinker bed horizontally while multiple controlled pressure fans force ambient air upwards through the material layer in distinct zones.
3. Efficient Heat Recovery: Hightemperature air from the hot zone is directed to the kiln as secondary air or to a calciner as tertiary air. Midtemperature air may be used for coal drying or other processes.
4. Final Quenching & Ахах: Fully cooled clinker is discharged via a crusher onto conveyor systems for transport to storage.
Хэрэглээний хамрах хүрээ: Designed for new dryprocess cement production lines or as a retrofit replacement for older planetary or firstgeneration grate coolers. Limitations include requirement for consistent feed sizing from the kiln and are typically engineered as part of a complete kiln system upgrade.
