Crushing and Quarrying in Sohar: A Hub for Aggregate Production

The Sultanate of Oman, particularly the industrial city of Sohar, has emerged as a key player in the Middle East’s construction and infrastructure sectors. With rapid urbanization and mega-projects like ports, highways, and commercial complexes, the demand for high-quality aggregates is soaring. Sohar’s quarries and crushing plants are pivotal in meeting this demand, leveraging advanced technology to produce sand, gravel, and crushed stone efficiently.

Industry Overview
Sohar’s quarrying sector benefits from abundant natural resources, including gabbro, limestone, and other hard rocks ideal for construction aggregates. The region’s strategic location near ports facilitates export to global markets. Modern crushing and screening equipment—such as jaw crushers, cone crushers, and vertical shaft impactors (VSIs)—are widely deployed to ensure optimal particle shape and gradation.

Core Equipment and Technology
1. Primary Crushing: Jaw crushers handle large rocks (e.g., 600–800mm feed size), reducing them to 150–300mm for secondary processing.
2. Secondary/Tertiary Crushing: Cone crushers or impactors refine the material further, producing 20–40mm aggregates for concrete or asphalt.
3. Sand Manufacturing: VSI crushers or high-pressure grinding rolls (HPGRs) create finely graded artificial sand, addressing the scarcity of natural sand.
4. Screening and Washing: Vibrating screens and sand washers remove impurities and ensure precise sizing.

Key Challenges and Solutions

  • Dust Control: Dry climates in Sohar necessitate enclosed crushing units and water sprinklers to comply with environmental regulations.
  • Hard Rock Abrasion: Tungsten carbide liners in crushers extend wear life.
  • Energy Efficiency: Hybrid or electric-driven systems reduce operational costs.

    • FAQ Section
    Q1: What types of crushers are best for gabbro in Sohar?
    A: Cone crushers with hydraulic adjustment excel in processing hard gabbro, offering consistent output and low maintenance.

    Q2: How to optimize sand production for concrete?
    A: VSI crushers with a closed-circuit system can achieve a fineness modulus of 2.6–3.0, ideal for Grade M25+ concrete.

    Q3: What’s the average output of a 200tph plant in Sohar?
    A: Depending on rock hardness, expect 160–180tph for limestone and 120–140tph for gabbro after accounting for downtime.

    Project Case Study
    A Sohar-based quarry supplying aggregates for the Duqm Port expansion utilized a 3-stage crushing setup:

  • Primary: CJ412 Jaw Crusher (1,200x800mm feed opening).
  • Secondary: CH430 Cone Crusher with automated settings.
  • Tertiary: CV218 VSI for shaped sand.

The plant achieved 250tph output with <15% fines, meeting ASTM C33 standards.

Conclusion
Sohar’s quarries are advancing with automation and sustainable practices. Investing in robust crushing systems and trained personnel ensures long-term competitiveness in Oman’s growing construction market.
