In bulk material handling, maintaining consistency in material quality is not just a preference—it’s a necessity. This is especially true for industries like cement, power generation, mining, steel, and ports, where variations in material composition can lead to costly inefficiencies in downstream processes. For operations that require both volume and uniformity, bridge-type scraper reclaimers have proven to be a highly effective and reliable solution for homogenized stockpile reclamation.

As a leading enterprise in bulk material handling systems and high-end metallurgical equipment, Dadi has consistently delivered innovative engineering and manufacturing capabilities that support large-scale, high-efficiency material processing systems. This article explores the functionality, advantages, and industrial applications of bridge-type scraper reclaimers, with a focus on how companies like Dadi are enabling the future of intelligent, automated stockpile management.

What Is a Bridge-type Scraper Reclaimer?

A bridge-type scraper reclaimer is a type of continuous reclaiming machine designed to recover bulk materials—such as coal, limestone, clay, or iron ore—from a longitudinal stockpile in a controlled and uniform manner.

Its key components include:

A rigid bridge structure that spans the width of the stockpile

A reclaimer trolley or carriage that moves across the bridge

Scraper chains or blades that cut and drag material onto a conveyor system

Automation and control systems for precise reclaiming rates

Unlike traditional front-end loaders or bucket reclaimers, bridge-type reclaimers operate on the principle of layer-by-layer reclaiming, ensuring a high degree of homogenization by consistently blending the material across the full cross-section of the stockpile.

Why Bridge-type Scraper Reclaimers Are Ideal for Homogenized Stockpiles

1. Consistent Material Quality

The primary advantage of bridge-type reclaimers is their ability to blend different material layers evenly. This is crucial in industries such as cement or steel, where raw material uniformity directly impacts product quality and production stability.

By reclaiming material horizontally and progressively, the reclaimer avoids the segregation issues commonly found in top-down or point-discharge systems.

2. Full Automation and Control

Modern bridge-type reclaimers are fully automated, with real-time control systems that monitor reclaiming speed, blade position, and conveyor loading. Dadi integrates intelligent control technologies, including PLC and SCADA systems, that allow remote operation, diagnostics, and performance optimization.

3. High Throughput Capacity

Bridge-type reclaimers are capable of handling large volumes of material with continuous reclaiming rates, making them ideal for large stockyards. They can be designed to meet throughput capacities exceeding 1,000 tons per hour, depending on the application.

4. Low Environmental Impact

Compared to mobile reclaimers, bridge-type systems produce less dust and noise, and do not require frequent heavy vehicle movement, which contributes to a cleaner and safer working environment.

5. Lower Operating Costs

With minimal moving parts and a static bridge structure, these reclaimers require less maintenance, offer longer service life, and reduce operational costs over time.

Industrial Applications of Bridge-type Scraper Reclaimers

1. Cement Plants

In cement production, raw materials like limestone, clay, and marl are stored and reclaimed from homogenization stockpiles. Bridge-type reclaimers ensure the feed to the kiln is chemically consistent, reducing kiln downtime and enhancing clinker quality.

2. Steel and Metallurgy

Iron ore, coal, and additives used in steel manufacturing must be consistently blended. Dadi’s reclaimers support high-efficiency sintering and blast furnace operations by delivering stabilized material streams to processing units.

3. Power Plants

Coal-fired power stations benefit from bridge reclaimers for feeding pulverizing mills with evenly mixed coal, helping to maintain combustion efficiency and minimize emissions.

4. Ports and Terminals

At large import/export terminals, bridge-type reclaimers help manage diverse material types with tight scheduling and blending requirements, especially when handling stockpiles for multiple clients.
