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 (т/ч) 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.

Предыстория проекта
Гранит, known for its durability and compressive strength, is an ideal material for road bases, производство бетона, и возведение фундамента. 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, 5-20мм, and 20-40mm aggregates—key sizes for infrastructure projects ranging from highway construction to residential developments.

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

2. Характеристики материала:
- Испытание: Local granite's high silica content (exceeding 65%) accelerated equipment wear.
- Решение: Adoption of multi-layered alloy steel wear parts in jaw crushers (например, JC98) и конусные дробилки (ХПТ300), extending component lifespan by 40% compared to standard models.

3. Логистические ограничения:
- Испытание: Underdeveloped transport networks increased equipment mobilization costs.
- Решение: Strategic use of semi-mobile crushing plants reduced foundation requirements by 60%, with key components designed for containerized shipping.

System Configuration & Workflow
The optimized three-stage crushing system combines efficiency with flexibility:

1. Первичное дробление:
- Оборудование: Щековая дробилка серии JC (JC110)
