Новая Каледония Производственная линия по дроблению никелевой руды производительностью 250 т/ч: Engineering Excellence in a Resource-Rich Region

New Caledonia, a French territory in the South Pacific, is globally renowned for its vast nickel reserves, accounting for approximately 10% of the world’s total nickel resources. The island’s unique geology and mineral-rich lateritic deposits make it a strategic hub for nickel mining and processing. To optimize resource extraction and meet growing global demand for stainless steel and battery materials, современный производительностью 250 тонн в час (т/ч) nickel ore crushing production line has been established. This article explores the technical design, операционная эффективность, and environmental considerations of this advanced production system.

Обзор проекта
The 250tph nickel ore crushing production line was designed to process lateritic nickel ore, characterized by its high moisture content, clay-like consistency, and variable hardness. The primary objectives were to achieve high throughput, ensure consistent particle size distribution for downstream processing, and minimize environmental impact in New Caledonia’s ecologically sensitive regions.

Компоненты & Workflow
1. Первичное дробление: Курсор челюсти
A heavy-duty jaw crusher serves as the first-stage crushing unit, reducing raw ore from a maximum feed size of 800mm to 150mm. Its robust design handles abrasive materials while resisting wear from silica content in laterites.

2. Вторичное дробление: Гидравлическая конусная дробилка
A multi-cylinder hydraulic cone crusher performs intermediate crushing, further reducing ore to 50mm. Advanced automation adjusts the closed-side setting (CSS) in real time to compensate for fluctuations in ore hardness.

3. Скрининг & Классификация: Вибрационные грохоты
A three-deck vibrating screen separates crushed material into three fractions:
- +50мм: Recirculated to secondary crusher
- 20–50 мм: Conveyed to tertiary crushing
- -20мм: Directly fed to stockpiles for transport

4. Третичное дробление: Ударная дробилка

For final size reduction, an impact crusher processes the 20–50mm fraction to achieve a uniform product of ≤15mm, optimized for leaching or smelting processes.

5. Система обработки материалов
Corrosion-resistant belt conveyors with dust suppression systems transport material between stages. Частотно-регулируемые приводы (VFD) enable energy-efficient speed adjustments based on feed rates.
