In industries that rely on efficient bulk material handling—such as cement, mining, steel, and power generation—the need for reliable reclaiming systems is paramount. One of the most effective and widely adopted machines for continuous and automated stockpile reclaiming is the Bridge-Type Scraper Reclaimer.
At the forefront of engineering and innovation in this field is Dadi, a company dedicated to the research, development, manufacturing, and integration of bulk material conveying equipment and high-end metallurgical machinery. With a strong foundation in industrial automation and system reliability, Dadi has become a trusted name in material handling solutions across demanding industrial sectors.
What Is a Bridge-Type Scraper Reclaimer?
A Bridge-Type Scraper Reclaimer is a mechanical device used for reclaiming bulk materials from a stockpile, typically stored in longitudinal piles within covered storage yards or blending beds. These machines are especially valuable in handling fine, free-flowing materials such as coal, limestone, ores, and raw meal in cement plants.
It operates as a fully automated system that moves along a fixed track, scraping material from the stockpile and delivering it to a conveyor belt system for downstream processing or transport.
Working Principle of the Bridge-Type Scraper Reclaimer
The core components of the bridge-type scraper reclaimer include:
Bridge Frame: A robust steel structure that spans the width of the pile and supports all moving parts.
Scraper Chain System: A series of chains with attached blades or scrapers that drag material from the pile towards the central conveyor.
Traveling Mechanism: Drives the bridge frame along the rails laid on both sides of the pile.
Tensioning System: Ensures proper chain alignment and effective material movement.
Control System: Enables automated operation, monitoring, and diagnostics.
How it works:
As the bridge travels across the pile lengthwise, the scraper chains—mounted beneath the bridge—rotate and scrape layers of material horizontally toward a central collecting point.
The collected material is then transferred to a belt conveyor system for continuous flow to processing units.
The operation is controlled via programmable logic controllers (PLCs), ensuring uniform reclaiming, minimal manpower, and low dust generation
Key Benefits of Bridge-Type Scraper Reclaimers
1. Uniform Material Blending
One of the greatest advantages is its ability to homogenize materials during reclaiming. This is crucial in industries like cement and steel, where consistent material quality affects final product performance.
2. High Efficiency and Automation
Bridge-type reclaimers operate continuously and automatically, reducing downtime and human intervention. With intelligent controls, they offer:
Automated start/stop
Load-based speed adjustments
Integrated safety systems
Dadi’s reclaimers come with smart control options for seamless integration into plant-wide automation systems.
3. Low Energy Consumption
Compared to bucket wheel or front-end loader systems, scraper reclaimers consume significantly less power. The operation is gentle and efficient, making them suitable for handling fine or dusty materials.
4. Environmentally Friendly Operation
Dadi engineers its reclaimers to minimize dust and noise, making them ideal for enclosed storage yards. This supports cleaner working environments and helps meet modern environmental regulations.
5. Long Service Life and Reliability
With robust structural design, wear-resistant materials, and low-speed mechanical components, Dadi’s bridge-type reclaimers offer:
Low maintenance requirements
Reduced wear-and-tear
Excellent operational reliability, even in 24/7 applications
