Coal Stacker Reclaimer System
The coal stacker reclaimer system is a fully integrated bulk material handling solution, designed to optimize stacking, storage, and reclaiming operations in power plants, ports, cement plants, and industrial yards. The system includes multiple key components: the stacker boom for precise coal placement, the bucket wheel for high-capacity reclaiming, conveyor belts for smooth material transport, travelling and slewing mechanisms for flexible movement, and a PLC-based automated control system for monitoring and remote operation.
With advanced design, the system ensures uniform stockpiles, continuous and efficient coal handling, reduced labor costs, and minimal downtime. Components are made from high-strength, wear-resistant materials to guarantee long-term reliability. Furthermore, the system can be fully customized in terms of boom length, bucket wheel diameter, rail layout, and automation features, making it adaptable to different yard sizes, coal types, and operational requirements.
Working Principle of Coal Stacker Reclaimer
Discover how our coal stacker reclaimers efficiently manage coal stockpiles with precision and automation. From layered stacking to homogenized reclaiming, every movement is designed to ensure continuous, reliable, and uniform coal handling for power plants, cement plants, and industrial yards.
Stacking Mode: In stacking mode, coal is transported from the main yard conveyor to the stacker reclaimer and transferred via its tail car to the boom stacker conveyor. The machine performs coordinated movements including longitudinal travelling along the track, boom slewing, and luffing. These precise movements allow the coal to be continuously and evenly deposited into long, regular piles with layered distribution. This layered stacking not only maximizes yard utilization but also creates the physical foundation for subsequent homogenized reclaiming, ensuring uniform quality in downstream processes.
Reclaiming Mode: In reclaiming mode, the rotating bucket wheel at the front of the boom becomes the key component. Multiple buckets scoop coal continuously across the pile cross-section. The material is discharged into the central chute at the top of the bucket wheel and transferred to the reclaiming conveyor beneath the boom. Coordinated longitudinal travelling and boom rotation allow the bucket wheel to extract coal in a “Z-shaped” or layered manner, ensuring material from different pile positions is thoroughly mixed. This homogenized reclaiming provides a continuous, stable, and uniform supply of coal to power plants, cement plants, or other processing facilities.
Automation and Control: All stacking and reclaiming operations can be monitored and controlled remotely via a PLC-based system. This enables automated operation, precise stockpile management, and reduced labor requirements, while maintaining high efficiency and safety in demanding industrial environments.
- Coal Stacker Reclaimer Advantages
The coal stacker reclaimer offers high efficiency, reliable operation, and precise material handling. Its design ensures uniform coal distribution, continuous processing, and reduced operational and maintenance costs.
Specialized Fuel Handling
The coal stacker reclaimer is designed for the unique characteristics of coal. Core components such as buckets and chutes use wear-resistant steel and anti-stick coatings, efficiently handling a wide range of coal types from bituminous to lignite, preventing material adhesion and blockage, and ensuring stable operation in power plants and cement plants.Optimized Homogenization for Fuel Stability
With precise layered stacking and cross-sectional reclaiming, the system mixes coal from different batches, reducing fluctuations in calorific value, moisture, and ash content. This ensures a stable fuel supply for boilers or cement kilns, improving combustion efficiency and reducing specific energy consumption and emissions.High Throughput and Continuous Operation
Continuous rotating bucket wheel reclaiming combined with high-speed conveyors achieves a throughput of several thousand tons per hour. Seamless integration with main plant conveyors allows 24/7 operation, meeting the demanding fuel supply requirements of power and clinker production lines.Advanced Automation and Intelligent Fuel Management
Fully integrable with plant DCS systems for unattended operation. The intelligent control system automatically plans optimal stacking and reclaiming paths and blending schemes based on production schedules, coal quality data, and inventory status, enabling precise fuel inventory management and cost optimization.Compact Design Reducing Fuel Storage Costs
A single machine integrates stacking, reclaiming, and mixing functions, saving significant investment, labor, and yard space compared to traditional bulldozer or loader-based solutions. High-density storage increases fuel capacity in limited space and reduces overall coal storage costs.

The machine is specifically optimized for handling various types of bulk coal, including but not limited to bituminous coal, sub-bituminous coal, lignite, and anthracite. Its core components (e.g., bucket wheel, chutes) feature special wear-resistant/anti-adhesion materials and designs, enabling efficient handling of coal with varying moisture content, particle size, and cohesiveness. This ensures continuous, high-efficiency operation in industrial settings like power plants and cement plants while minimizing material buildup and blockages.
Compared to traditional intermittent methods, the stacker-reclaimer’s core advantages lie in its continuity, automation, and cost-effectiveness:
Continuous & Efficient: The bucket wheel provides continuous reclaiming, with handling capacities reaching thousands of tons per hour—far exceeding wheel loaders—enabling 24/7 fuel supply.
Automatic Blending: Its programmed “chequer stacking, blending reclaiming” process automatically homogenizes coal to stabilize fuel quality, a function impossible for traditional equipment.
Lower Total Cost of Ownership: A single machine integrates stacking, reclaiming, and blending. Over the long term, its labor, energy, and maintenance costs are significantly lower than traditional setups requiring multiple machines, offering a superior return on investment.
Absolutely. We provide comprehensive engineering customization services. All key parameters—including the rail span (stockyard width), boom length (operating radius), handling capacity (tons/hour), and discharge conveyor interface—can be tailored to your specific yard layout, storage volume, and process flow requirements to deliver the most optimized and integrated solution.
Features include automatic collision avoidance, emergency stop systems, overload protection, and remote monitoring, ensuring safe operation and reducing risks for operators.
Yes. It can be seamlessly connected with conveyors, feeders, silos, and the plant’s DCS/PLC system for fully automated fuel handling and stockyard management.
