Efficient bulk material handling is essential for maintaining stable production in industries such as steelmaking, cement manufacturing, power generation, and mining. As industrial facilities handle increasing volumes of raw materials, efficient storage, reclaiming, and blending systems become increasingly important.

A bridge-type scraper reclaimer is an effective solution for recovering bulk materials from longitudinal stockpiles while maintaining consistent material quality. With its specialized scraper design, automated operation, and high reclaiming capacity, this equipment helps improve stockyard efficiency and support continuous industrial production.

What Is a Bridge-Type Scraper Reclaimer?

A bridge-type scraper reclaimer is a large-scale material handling machine designed to recover bulk materials from stockpiles created by stacking equipment. It typically consists of a bridge structure spanning the stockyard, scraper mechanisms, drive systems, and a discharge conveyor.

Unlike conventional reclaiming equipment that operates mainly on a single working face, a bridge-type scraper reclaimer uses reciprocating scraper systems to recover materials from different directions.

This design is particularly suitable for longitudinal blending stockyards, where consistent material composition is important for downstream production processes.

Key Features of Bridge-Type Scraper Reclaimers

1. Dual-Scraper Design

One of the main characteristics of bridge-type scraper reclaimers is their dual-scraper configuration. The two scraper systems move back and forth along the stockpile, allowing materials to be recovered from different layers.

This arrangement supports efficient reclaiming and helps combine materials deposited during successive stacking operations.

2. High Reclaiming Capacity

Bridge-type scraper reclaimers can be designed with reclaiming capacities of approximately 500–3,200 tonnes per hour, depending on project requirements.

Rail spans generally range from 30 to 60 metres, making the equipment suitable for large industrial stockyards. Actual specifications depend on material density, stockpile dimensions, and required throughput.

3. Automated Control Systems

Modern equipment can incorporate PLC-based control systems to coordinate scraper movement, conveyor operation, and machine travel.

Sensors, protective interlocks, and fault alarms help monitor operating conditions and improve equipment safety. Remote monitoring and automated operating sequences can also reduce manual intervention.

How Does a Bridge-Type Scraper Reclaimer Improve Material Blending?

Material blending is essential in industries where raw material composition directly affects production quality.

During stacking, bulk materials are deposited in multiple layers across the stockyard. When reclaiming begins, the scraper system removes materials across these layers according to a controlled operating sequence.

Different material layers are therefore combined on the discharge conveyor, helping reduce variations in the reclaimed material composition.

This process is particularly valuable in cement manufacturing, where limestone and other raw materials require consistent blending before grinding and kiln processing.

Effective blending depends on stockpile geometry, stacking methods, material characteristics, and reclaiming control. When these factors are properly coordinated, the system can provide more stable material feeding for continuous production.

Main Industrial Applications

Steel Plants: Bridge-type scraper reclaimers are widely used for handling iron ore fines, pellets, lump ore, coal, coke, and other raw materials. Consistent reclaiming helps maintain a stable supply to steel production processes.

Power Plants: In thermal power stations, these machines recover coal from storage stockpiles and transfer it to downstream conveyor systems, supporting continuous fuel supply.

Cement Plants: Limestone and other raw materials can be stacked in layers and reclaimed through controlled blending, helping improve raw material consistency before processing.

Mining and Ports: Large stockyards use scraper reclaimers to handle ores, minerals, and other bulk commodities efficiently.

Structural Design and Important Components

Reliable equipment performance depends on structural strength and component quality.

The main bridge structure may use high-strength steels such as Q345B and Q355E, while wear-resistant materials such as HARDOX can be applied to components exposed to abrasive bulk materials.

Other important components include motors, gearboxes, bearings, scraper chains, and electrical control systems. Depending on project specifications, equipment may incorporate internationally recognized components from brands such as Siemens, SEW, SKF, and Schneider Electric.

For outdoor applications, equipment can also be engineered to operate in demanding temperature environments, provided that suitable materials, lubrication systems, and electrical components are selected.

How to Choose the Right Bridge-Type Scraper Reclaimer

Selecting suitable equipment requires evaluating several technical factors.

First, consider the characteristics of the materials being handled, including particle size, bulk density, moisture content, and abrasiveness.

Second, determine the required reclaiming capacity, stockpile dimensions, rail span, and available installation space.

Third, evaluate the automation requirements and compatibility with existing stacking machines, conveyors, and centralized control systems.

Finally, pay attention to structural design, wear protection, component reliability, maintenance accessibility, and after-sales technical support.

A customized equipment solution based on actual operating conditions can help improve long-term efficiency and reduce unnecessary maintenance costs.
