The Complete Guide to Bridge-Type Scraper Reclaimers for Bulk Ore and Mineral Handling

26 May.2026

Efficient bulk material handling is essential for mining, metallurgy, ports, power plants, and mineral processing facilities. Among the various stockyard reclaiming systems available today, the bridge-type scraper reclaimer stands out for its reliability, continuous operation, and ability to handle large volumes of bulk materials with high efficiency.

Designed to recover and transport ores, minerals, coal, limestone, and other bulk materials from storage stockpiles, bridge-type scraper reclaimers play a critical role in ensuring a stable material supply for downstream production processes. This comprehensive guide explores the working principles, components, advantages, applications, and selection criteria of bridge-type scraper reclaimers while highlighting the expertise of Jiangyin Dadi Equipment Co., Ltd. in bulk material handling and metallurgical equipment solutions.

Bridge-type Scraper Reclaimer

What Is a Bridge-Type Scraper Reclaimer?

A bridge-type scraper reclaimer is a large-scale bulk material handling machine designed to reclaim materials stored in stockyards. The equipment operates by moving a scraper chain system across a stockpile, continuously collecting material and transporting it onto a conveyor system for further processing.

The machine typically consists of a bridge structure spanning the storage pile, along with scraper mechanisms that move along the stockpile surface. This design enables efficient material recovery while maintaining consistent blending and homogenization of bulk materials.

Bridge-type scraper reclaimers are widely used in industries that require controlled material extraction from stockpiles while ensuring uninterrupted production operations.

The Importance of Efficient Reclaiming Systems

In modern industrial facilities, stockyards serve as critical storage and buffering areas between raw material supply and production processes.

An effective reclaiming system helps achieve:

  • Continuous material flow
  • Improved stockyard utilization
  • Reduced manual handling
  • Better material homogenization
  • Enhanced operational efficiency
  • Lower operating costs
  • Stable production processes

Bridge-type scraper reclaimers are particularly effective in applications where material consistency and controlled reclaiming rates are essential.

Working Principle of a Bridge-Type Scraper Reclaimer

The operation of a bridge-type scraper reclaimer is based on a simple yet highly efficient reclaiming process.

Material Storage

Bulk materials are stacked into longitudinal stockpiles using stacking equipment such as stackers or stacker-reclaimers.

Bridge Movement

The bridge structure travels along rails installed on both sides of the stockyard, allowing the machine to cover the entire stockpile length.

Scraper Operation

Scraper chains mounted beneath the bridge move across the pile surface, gradually removing material layer by layer.

Material Collection

The scraped material is directed toward a central collection hopper or receiving conveyor.

Material Transportation

The reclaimed material is transferred onto downstream conveyor systems that transport it to processing plants, blast furnaces, sintering facilities, crushing stations, or other production units.

This continuous reclaiming process ensures a steady material supply while minimizing stockpile segregation.

Main Components of a Bridge-Type Scraper Reclaimer

Understanding the major components of the equipment helps operators and plant managers evaluate system performance and maintenance requirements.

Bridge Structure

The bridge serves as the primary support framework of the machine. It spans the stockpile and carries all major operational components.

Key characteristics include:

  • High structural strength
  • Excellent stability

Traveling Mechanism

The traveling system allows the machine to move longitudinally along the stockyard.

Components may include:

  • Rail-mounted wheels
  • Drive motors
  • Gearboxes
  • Position control systems

Material Collection Hopper

The hopper receives material from the scraper system and directs it toward conveying equipment.
