Advanced Slag Grinding Equipment Exported to Ethiopia

Ethiopia is rich in mineral resources, including iron ore, coal, and silica, providing favorable conditions for the development of local steel and construction materials industries. In recent years, the Ethiopian government has actively promoted industrialization, encouraging foreign investment in infrastructure construction and manufacturing. Against this backdrop, our company successfully exported a set of advanced slag grinding equipment to Ethiopia, assisting local enterprises in enhancing production efficiency and product quality.

Equipment Selection and Supply

After in-depth technical exchanges and demand analysis, we recommended the vertical roller mill to the client. This equipment offers high efficiency, energy savings, a small footprint, and easy operation and maintenance, making it particularly suitable for ultra-fine grinding of slag. The supply scope includes:

• Vertical roller mill main unit
• Powder classifier
• High-efficiency dust collection system
• Electrical control system
• Related auxiliary equipment

Production Process Flow

1. Crushing Stage: Large pieces of slag are crushed by a jaw crusher to a size suitable for grinding (15mm-50mm).
2. Grinding Stage: The crushed slag is conveyed to the raw material silo via a bucket elevator, then fed evenly into the vertical roller mill by a quantitative feeder for grinding.
3. Classification Stage: The ground material is classified by the powder classifier; coarse powder that does not meet the requirements is returned to the mill for regrinding, while qualified fine powder proceeds to the next process.
4. Collection Stage: The qualified slag micro powder is collected by the high-efficiency dust collection system, enters the finished product silo, and is finally packaged or stored in bulk.

Project Outcomes

After equipment installation and commissioning, the operation has been stable, with output and product quality meeting expected targets. The produced slag micro powder has a specific surface area of over 400㎡/kg, meeting the S95 grade concrete standard, and is widely used in local infrastructure construction projects.

Through this cooperation, our company provided advanced slag grinding solutions to Ethiopian steel enterprises, aiding local industrial upgrading and sustainable development. We look forward to collaborating with more Ethiopian enterprises in the future to promote local economic prosperity and progress.
