200 TPH River Stone Crushing Plant In Eritrea

Client Overview

Our client in Eritrea operates a large-scale construction and quarrying business, focusing on producing high-quality sand and aggregates for infrastructure projects. Facing increasing demand for construction materials, they sought a reliable crushing solution capable of processing 200 tons of river stone per hour into uniform-sized aggregates.

Project Background

River stones are hard-wearing materials, requiring durable and efficient crushing equipment. The Eritrean customer needed a complete sand production line that could withstand abrasive conditions while delivering high capacity and consistent particle size distribution.

Challenges

• Material Hardness: River stones are tough, requiring wear-resistant crushing machines.
• High Capacity Demand: The plant needed stable operation at 200TPH without frequent breakdowns.
• End Product Quality: The aggregates had to meet strict standards for construction use.

Solution: Liming Heavy Industry’s Sand Production Line

Our engineers designed a tailored crushing and screening plant featuring primary jaw crushing, secondary cone crushing, and sand shaping to maximize productivity and particle shape.

Equipment Configuration

1. Vibrating Feeder (GZD1100×4200)
   • Ensures smooth and controlled feeding into the crusher.
   • Prevents raw material jams and enhances crusher efficiency.
2. C6X Jaw Crusher (C6X125) – Primary Crushing
   • Handles large river rocks (≤750mm) effortlessly with deep crushing chamber.
   • High crushing ratio minimizes bottlenecking.
3. HPT Hydraulic Cone Crusher (HPT300) – Secondary Crushing
   • Ensures finer and more uniform discharging (≤45mm).
   • Fully automatic hydraulic adjustment reduces downtime.
4. VSI6X Sand Maker (VSI6X1150) – Tertiary Crushing & Shaping
   • Produces high-quality manufactured sand with excellent gradation.
   • Enhances cubical shape for superior concrete mixtures.
5. S5X Vibrating Screen (S5X2460-3) – Screening & Grading
   • Efficiently separates aggregates into multiple fractions (0-5mm, 5-10mm, 10-20mm, 20-45mm).
   • Heavy-duty screen decks improve longevity in abrasive operations.
6. Belt Conveyors (B6X)
   • Facilitates seamless material transfer between crushing stages.

Technical Highlights

• Automated Lubrication System: Ensures smooth operation of crushers and screens.
• Dust Suppression Integration: Reduces airborne particles for environmental compliance.
• Energy-Efficient Motors: Lowers operational costs while maintaining high output.

Project Results

• Achieved 200TPH production capacity consistently.
• Final sand & aggregates met ASTM and ISO standards.
• Reduced maintenance costs through wear-resistant liners & automated monitoring.
