In large-scale industrial operations, bulk material handling is rarely just a supporting process—it often determines overall production stability. Industries such as steel, mining, cement, power generation, and port logistics rely on continuous, well-controlled material flow to keep downstream systems running smoothly.
For longitudinal blending stockyards, the bridge-type scraper reclaimer has proven to be a reliable and efficient solution. Designed for high-capacity reclaiming and consistent blending, it helps operators manage large volumes of bulk materials while maintaining stable composition. With extensive experience in bulk material handling systems, Dadi Engineering provides bridge-type scraper reclaimer solutions that focus on long-term operational performance rather than short-term output alone.
Understanding the Bridge-Type Scraper Reclaimer
A bridge-type scraper reclaimer is a heavy-duty reclaiming machine commonly installed in longitudinal blending stockyards. It works together with a stacker, which builds stockpiles in layers. The reclaimer then recovers material continuously across the pile width, ensuring a steady and well-blended output.
This type of equipment is suitable for handling a wide range of bulk materials, including:
-
Iron powder
-
Lump ore
-
Coal
-
Flux
-
Pellets
-
Coke and similar materials
Its bridge structure and scraper system allow it to operate efficiently even in wide stockyards, where stable reclaiming and blending quality are critical.
Working Principle and Operation Mode
Designed for Longitudinal Blending Stockyards
In a typical system, the stacker builds the stockpile using layered stacking methods. This stacking pattern lays the foundation for effective blending during reclaiming.
Flexible Forward and Backward Reclaiming
The bridge-type scraper reclaimer with double harrow travels along rails installed on both sides of the stockyard. It can move forward or backward to reclaim material from different directions, making it possible to:
-
Reclaim material from both the front and rear of the stockpile
-
Carry out stacking and reclaiming at the same time
-
Maintain continuous material supply without interrupting yard operations
In real production environments, this flexibility significantly improves stockyard utilization and reduces idle time for downstream conveyors and processing systems.
Key Technical Parameters
Dadi’s bridge-type scraper reclaimer solutions are engineered to cover a wide range of operational requirements:
-
Material Type: iron powder, lump ore, coal, flux, pellet, coke, etc.
-
Reclaiming Capacity: 500–3200 t/h
-
Rail Span Range: 30–60 m
These parameters allow the equipment to be adapted to different yard sizes, material characteristics, and production capacities, whether for medium-scale plants or large industrial complexes.
Practical Advantages in Daily Operation
From an operator’s point of view, the value of a bridge-type scraper reclaimer lies in its performance over years of continuous use:
High Reclaiming Capacity with Stable Material Flow
The system delivers large reclaiming capacity while keeping material flow smooth and predictable. This stability helps reduce load fluctuations in belt conveyors and downstream equipment.
