South Sudan's 200-250tph Granite Crushing Line: A Milestone in Infrastructure Development

South Sudan, the world's youngest nation, faces significant challenges in building critical infrastructure to support its economic growth and societal needs. Against this backdrop, the establishment of a 200-250 ton-per-hour (tph) granite crushing line marks a pivotal step toward addressing the country's demand for high-quality construction aggregates. This project not only demonstrates technical innovation but also highlights the potential for sustainable resource utilization in challenging environments.

Bối cảnh dự án
đá granit, known for its durability and compressive strength, is an ideal material for road bases, sản xuất bê tông, và xây dựng nền móng. South Sudan's abundant granite reserves presented an opportunity to reduce reliance on imported construction materials while stimulating local industries. The crushing line was designed to process raw granite into 0-5mm, 5-20mm, and 20-40mm aggregates—key sizes for infrastructure projects ranging from highway construction to residential developments.

Technical Challenges & Giải pháp
1. Harsh Operating Conditions:
- Thử thách: Limited access to stable power grids and extreme seasonal weather fluctuations.
- Giải pháp: Implementation of diesel-electric dual-power mobile crushing stations ensured uninterrupted operation. Modular design allowed rapid deployment and relocation as project demands shifted.

2. Đặc tính vật liệu:
- Thử thách: Local granite's high silica content (vượt quá 65%) accelerated equipment wear.
- Giải pháp: Adoption of multi-layered alloy steel wear parts in jaw crushers (ví dụ., JC98) và máy nghiền hình nón (HPT300), extending component lifespan by 40% compared to standard models.

3. Ràng buộc hậu cần:
- Thử thách: Underdeveloped transport networks increased equipment mobilization costs.
- Giải pháp: Strategic use of semi-mobile crushing plants reduced foundation requirements by 60%, with key components designed for containerized shipping.
