Project Overview

A large-scale open-pit iron ore mining project in West Africa involved the construction of a new crushing, screening, and mineral processing production line.The project required a comprehensive supply of wear-resistant steel materials, structural steel sections, and grinding media to support the installation and operation of critical mining equipment.
The material package included NM450 wear-resistant steel plates for crusher and hopper liners, S355JR structural steel sections for conveyor galleries and equipment support structures, and high-chromium alloy grinding balls for ball milling applications.
With European-standard project acceptance requirements, the customer placed particular emphasis on material quality, hardness verification, mechanical testing documentation, and prefabrication support.
The steel plates also required cutting and bending according to project drawings to facilitate subsequent equipment fabrication and installation.

Project Requirements

Mining equipment operates under demanding conditions involving continuous material handling, abrasion, impact, and mechanical loading.
For this open-pit iron ore project, the customer required a coordinated material supply solution addressing three major requirements:

• Wear Resistance: NM450 steel plates for crusher and hopper liners exposed to abrasive iron ore handling.
•  Structural Support: S355JR H beams and channel steel for conveyor galleries and equipment protection supports.
•  Grinding Media: High-chromium alloy grinding balls for the mineral processing line.

The project also required complete mechanical property and hardness test reports, inspection documentation, and steel plate prefabrication based on approved drawings.

Project Solution

1. NM450 Wear-Resistant Steel Plates for Crusher and Hopper Liners
Crusher and hopper components are exposed to continuous contact with abrasive iron ore during material feeding, crushing, and transfer operations.
To meet the project’s wear protection requirements, two thicknesses of NM450 wear-resistant steel plates were supplied:

•  16 mm plates, totaling 245 tons
• 25 mm plates, totaling 138 tons

The plates were intended for crusher and hopper liner fabrication, providing wear-resistant surfaces in areas subject to frequent material contact.
Hardness verification and ultrasonic inspection were completed, with the supplied plates meeting the project’s inspection requirements.
According to the customer’s fabrication drawings, the plates were also cut and bent before delivery, supporting subsequent liner manufacturing and installation.

2. S355JR Structural Steel for Conveyor Galleries
The mineral processing production line required structural steel components for conveyor galleries connecting material handling and processing equipment.
For this application, S355JR HN350 × 175 × 7 × 11 mm H beams were supplied in fixed 12-meter lengths.
A total of 96 tons of H beams supported the project’s conveyor gallery structural requirements.
In addition, 52 tons of S355JR No. 20 hot-rolled channel steel were supplied for equipment protection support structures.
Both structural steel categories were specified according to EN 10025, aligning with the project’s European-standard acceptance requirements.

3. High-Chromium Grinding Balls for Mineral Processing
Grinding media formed another important part of the material supply package.
The project included 160 tons of Φ80 mm high-chromium alloy grinding balls for ball milling operations in the iron ore processing line.
For this application, consistent grinding media quality was important to the customer’s operational requirements.
The supplied grinding balls achieved an acceptable breakage performance under the project’s acceptance criteria, supporting the successful commissioning of the mineral processing line.

4. Material Inspection and Prefabrication Support
In addition to raw material supply, the project required documentation and processing support to match equipment manufacturing requirements.
The supply scope addressed:

• Mechanical property and hardness inspection documentation
• Ultrasonic inspection of wear-resistant steel plates
• Steel plate cutting according to project drawings
•  Plate bending and prefabrication
•  Coordination of multiple steel and grinding media categories

These services helped the customer receive materials prepared for downstream fabrication, reducing the need for additional cutting and forming work.

Project Results

The project achieved the required material inspection and delivery outcomes, supporting the successful commissioning of the complete crushing and mineral processing production line.

Quality Inspection and Acceptance
All supplied NM450 wear-resistant steel plates met the specified hardness and ultrasonic inspection requirements.
The project also required mechanical property and hardness test documentation to support European-standard acceptance procedures.

Customized Steel Plate Prefabrication
Wear-resistant steel plates were cut and bent according to the customer’s fabrication drawings.
This processing support helped streamline downstream manufacturing and preparation for equipment installation.

Grinding Media Performance
The supplied high-chromium alloy grinding balls demonstrated controlled breakage performance, meeting the project’s operational expectations.

Successful Production Line Commissioning
The complete crushing and mineral processing production line was successfully commissioned.
The service life of the wear-resistant liners met the project owner’s expectations, demonstrating their suitability for the intended mining applications.
