As a dedicated provider of bulk material handling solutions, Dadi Equipment Co., Ltd. understands the critical role efficient and reliable machinery plays in various industries. Semi-portal scraper reclaimers are a vital component in modern material handling, offering a compact and effective solution for reclaiming materials from stockpiles. This comprehensive guide explores the design, functionality, benefits, and applications of semi-portal scraper reclaimers, highlighting their significance in optimizing material handling processes.

What is a Semi-Portal Scraper Reclaimer?

A semi-portal scraper reclaimer is a type of bulk material handling equipment designed to reclaim materials from longitudinal or circular stockpiles. It is a variation of the portal reclaimer, but instead of a full portal structure, one side of the reclaimer is supported by a retaining wall or a central column. This design makes it more compact and suitable for covered storage facilities or situations where space is limited. The primary function of a semi-portal scraper is to collect and redistribute bulk material from temporary storage piles onto a conveyor system for further processing or transportation.

Key Components of a Semi-Portal Scraper Reclaimer

Portal Structure: The main body of the reclaimer that spans the stockpile. In a semi-portal design, one side is supported by a rail on a retaining wall or central column.

Scraper Arm: Equipped with chains, blades, or buckets, the scraper arm reaches across the stockpile to collect material.

Traveling Mechanism: Allows the reclaimer to move along the stockpile, either on a longitudinal track or around a circular storage area. This mechanism typically consists of traveling gears or trucks.

Drive System: Powers the scraper arm and the traveling mechanism, ensuring efficient material collection and movement.

Conveyor System: Receives the reclaimed material from the scraper arm and transports it to the next stage of processing or storage.

How Semi-Portal Scraper Reclaimers Work

Semi-portal scraper reclaimers operate by moving along a track above the stockpile. The scraper arm extends across the pile, and a chain system equipped with blades or buckets rotates to scrape the surface of the material. The collected material is then discharged onto a belt conveyor, which carries it away for further processing. The reclaiming process can be automated using programmable logic controllers (PLCs), allowing for continuous operation without manual intervention.

In circular stockyards, the portal is supported on one side by a ball-bearing slewing ring at the center column and on the other side by an undercarriage on a ring rail.

Advantages of Using Semi-Portal Scraper Reclaimers

Compact Design: The semi-portal design is more compact than full-portal reclaimers, making it ideal for covered storage facilities and space-constrained environments.

Efficient Material Handling: Semi-portal scrapers provide efficient and reliable material handling, ensuring a consistent flow of material from storage to processing.

Automated Operation: The ability to automate the reclaiming process reduces the need for manual labor and increases operational efficiency.

Versatility: Semi-portal reclaimers can handle a wide range of bulk materials, including coal, limestone, gypsum, iron ore, and woodchips.

Reduced Dust Emission: These reclaimers are perfect for indoor applications, and storage solutions fulfill even the most stringent environmental requirements.

Cost-Effectiveness: By optimizing material handling, semi-portal reclaimers can reduce operational costs and improve overall productivity.

Blending Capabilities: Can be used in blending beds with up to 400 layers achieving blending ratios of up to 10:15.

Common Applications of Semi-Portal Scraper Reclaimers

Power Plants: Handling materials such as limestone, coal, and gypsum.

Mining: Reclaiming various ores and minerals from stockpiles.

Cement Production: Managing raw materials like limestone and clinker.

Fertilizer Industry: Handling fertilizers such as urea and ammonium nitrates.

Wood Processing: Managing woodchips and other wood-based materials.

Sinter Plants: Handling sinter, iron ore, and additives.
