Dây chuyền nghiền đá granite Congo 80tph: A Case Study in Efficient Aggregate Production

Giới thiệu
The Democratic Republic of the Congo (DRC), endowed with abundant mineral resources, has seen growing demand for infrastructure development in recent years. To support construction projects, the need for high-quality aggregates has surged. One notable example is the establishment of an 80-ton-per-hour (tph) granite crushing line in the region. This project exemplifies how tailored engineering solutions can overcome logistical and operational challenges while delivering sustainable results. Đây, we explore the design, thực hiện, and outcomes of this critical infrastructure initiative.

Bối cảnh dự án
đá granit, a durable and versatile material, is widely used in road construction, xây dựng nền móng, and concrete production. In the DRC’s resource-rich but infrastructure-limited environment, setting up a reliable crushing plant required addressing multiple challenges:
1. Power Supply Limitations: Unstable grid electricity necessitated energy-efficient equipment and backup power solutions.
2. Logistical Constraints: Remote locations demanded modular, transportable machinery to reduce setup time and costs.
3. Cân nhắc về môi trường: Minimizing dust, tiếng ồn, and water pollution was critical to comply with local regulations and community expectations.

Crushing Line Design & Equipment Configuration
The 80tph granite crushing line was engineered to maximize efficiency while adapting to local conditions. Cấu hình bao gồm:

1. Giai đoạn nghiền sơ cấp:
- Máy nghiền hàm mạnh mẽ (ví dụ., PE600×900) processes raw granite blocks (500mm) into coarse aggregates. Its simple structure ensures reliability in high-dust environments.

2. Giai đoạn nghiền thứ cấp:
- Máy nghiền hình nón thủy lực (ví dụ., HPT300) further reduces material size to ≤40mm. Its automated adjustment system optimizes particle shape and throughput.

3. Screening & Conveying:
- Multi-layer vibrating screens classify aggregates into 0-5mm, 5-15mm, and 15-31.5mm specifications for diverse applications.
- Belt conveyors with dust covers ensure seamless material transfer while mitigating environmental impact.

4. Hệ thống điện:
- Diesel generators supplement grid power to maintain uninterrupted operations during outages.

Key Innovations & Adaptations
1. Thiết kế mô-đun: Pre-assembled components reduced on-site installation time by 30%, crucial for remote areas with limited technical support.
2. Ngăn chặn bụi: Water spray
