In industries such as mining, power generation, cement, and metallurgy, the efficient handling of bulk materials is critical to operational success. One of the most effective solutions for reclaiming bulk materials from stockpiles—especially in longitudinal storage yards—is the semi-portal scraper reclaimer.

Whether you’re upgrading your material handling systems or planning a new facility, implementing a semi-portal scraper reclaimer can drastically improve efficiency, reduce operational costs, and enhance automation. This guide provides a step-by-step overview of how to implement these machines successfully in your operation, and how Dadi, a leader in bulk material and metallurgical equipment, supports clients through this process.

What Is a Semi-Portal Scraper Reclaimer?

A semi-portal scraper reclaimer is a type of stockyard equipment used to continuously reclaim bulk materials like coal, limestone, and iron ore from a storage pile. It consists of a portal structure that spans part of the stockpile area and operates with a scraper arm that travels along the pile, collecting material and feeding it onto a conveyor belt.

Unlike full-portal reclaimers, semi-portal units are ideal for facilities with limited space or asymmetrical stockpile layouts.

Benefits of Using a Semi-Portal Scraper Reclaimer

Efficient Continuous Reclaiming: High reclaim rates with minimal energy consumption.

Reduced Labor and Maintenance: Designed for automated and unmanned operation.

Space-Saving: Requires less structural footprint than full-portal reclaimers.

Blending Capabilities: Offers consistent material mixing and homogenization.

Enhanced Safety: Minimizes human interaction with large stockpiles and moving equipment.

Step-by-Step Implementation Guide

Step 1: Define Operational Requirements

Begin by identifying your material handling needs:

Type of material (density, moisture content, abrasiveness)

Daily throughput

Storage yard layout

Desired reclaim capacity and blending quality

Integration with existing conveyors or systems

Dadi’s engineering team works closely with clients during this phase to ensure that the reclaimer configuration matches their production flow and material properties.

Step 2: Site Survey and Feasibility Study

A thorough site analysis is essential. This includes:

Topographic surveying

Soil bearing capacity analysis

Review of weather/environmental factors

Assessment of infrastructure compatibility

Dadi provides on-site consulting and technical feasibility reports as part of its comprehensive pre-project services.

Step 3: Custom Design and Engineering

With requirements established, the next step is to develop a customized reclaimer solution. This includes:

Structural design of the semi-portal frame

Selection of scraper chains and travel mechanisms

Dust and spillage control systems

Electrical and automation systems

Dadi specializes in bespoke design, offering tailored solutions that meet local and international standards (such as GB, ISO, or DIN norms).

Step 4: Manufacturing and Quality Control

Once the design is finalized, manufacturing begins. This includes:

Steel structure fabrication

Assembly of mechanical components

Factory acceptance testing (FAT)

Dadi ensures stringent quality control, utilizing advanced CNC machining, robotic welding, and certified materials to guarantee reliability and longevity.

Step 5: On-Site Installation and Commissioning

Installation involves:

Groundwork and foundation setting

Mechanical and electrical assembly

Calibration of sensors and drive systems

System integration and testing

Dadi’s experienced installation team and engineers provide full on-site supervision, ensuring that the system operates as intended.

Step 6: Training and Handover

Before full operation, personnel must be trained in:

Equipment operation

Safety protocols

Preventive maintenance routines

Troubleshooting procedures

Dadi provides detailed operation manuals, training programs, and after-sales support to empower your team with the knowledge needed for long-term success.

Step 7: Maintenance and Lifecycle Support

Even the most robust systems require maintenance. Dadi offers:

Preventive maintenance schedules

Spare parts management

Remote diagnostics and performance monitoring

Upgrades and system optimization
