Ligne de concassage de granit de 250 tph en Afrique du Sud: Un modèle d’efficacité et de durabilité

Granit, renowned for its durability and aesthetic appeal, is one of the most widely used materials in construction and infrastructure development. In South Africa, a country rich in mineral resources, the demand for high-quality granite aggregates has surged alongside rapid urbanization and industrial growth. To meet this demand, a state-of-the-art 250-ton-per-hour (tph) granite crushing line was established, showcasing cutting-edge technology and operational excellence. This article explores the design, mise en œuvre, and significance of this project.

Aperçu du projet
The 250tph granite crushing line in South Africa was designed to process large blocks of raw granite into aggregates of varying sizes for use in road construction, production de béton, et applications architecturales. Located in a region abundant with granite reserves, the project prioritizes efficiency, environmental sustainability, and cost-effectiveness. By leveraging advanced machinery and optimized workflows, the facility ensures consistent output while minimizing downtime and operational costs.

Equipment and Configuration
The success of the crushing line hinges on a well-planned combination of equipment tailored to handle granite's high hardness and abrasiveness:
1. Concassage primaire: A robust jaw crusher serves as the primary crushing unit, reducing large granite blocks (up to 630mm) into smaller pieces (≤150mm). Its high crushing ratio and sturdy structure make it ideal for handling tough materials.
2. Concassage secondaire: A hydraulic cone crusher is employed for intermediate crushing, further refining the material to ≤40mm. Its automated adjustment system ensures precise control over particle size.
3. Concassage Tertiaire: A multi-cylinder hydraulic cone crusher performs fine crushing to produce aggregates as small as ≤19mm. This stage enhances product gradation for specialized applications.
4. Screening and Sorting: Multiple vibrating screens classify the crushed material into different specifications (par ex., 0-5mm, 5-10mm, 10-20mm). Oversized particles are recirculated to ensure zero waste.
5. Système de suppression de poussière: Advanced spray nozzles and enclosures mitigate dust emissions, aligning with South Africa’s stringent environmental regulations.

Technical Highlights
1. Automation Integration: The entire production line is controlled by an intelligent PLC system that monitors equipment performance in real time. Automated alerts for maintenance reduce unplanned downtime.
2. Efficacité énergétique: Variateurs de fréquence (VFD) optimize power consumption across motors and crushers, cutting energy
