Linha de britagem de granito Congo 80tph: A Case Study in Efficient Aggregate Production

Introdução
A República Democrática do Congo (RDC), 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. Aqui, we explore the design, implementação, and outcomes of this critical infrastructure initiative.

Histórico do projeto
Granito, a durable and versatile material, is widely used in road construction, building foundations, 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. Considerações Ambientais: Minimizing dust, barulho, 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. A configuração inclui:

1. Estágio de britagem primária:
- Um britador de mandíbula robusto (por exemplo, PE600×900) processes raw granite blocks (≤500mm) into coarse aggregates. Its simple structure ensures reliability in high-dust environments.

2. Estágio de britagem secundária:
- Um britador de cone hidráulico (por exemplo, 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, 5-15milímetros, and 15-31.5mm specifications for diverse applications.
- Belt conveyors with dust covers ensure seamless material transfer while mitigating environmental impact.

4. Sistema de energia:
- Diesel generators supplement grid power to maintain uninterrupted operations during outages.

Key Innovations & Adaptations
1. Projeto Modular: Pre-assembled components reduced on-site installation time by 30%, crucial for remote areas with limited technical support.
2. Supressão de poeira: Water spray
