Dây chuyền sản xuất quặng niken 250tph Caledonia mới: 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, a state-of-the-art 250-ton-per-hour (tph) nickel ore crushing production line has been established. This article explores the technical design, hiệu quả hoạt động, and environmental considerations of this advanced production system.

Tổng quan dự án
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.

Linh kiện & Quy trình làm việc
1. Nghiền sơ cấp: lời nguyền hàm
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. Nghiền thứ cấp: Máy nghiền côn thủy lực
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. Sàng lọc & Phân loại: Màn hình rung
A three-deck vibrating screen separates crushed material into three fractions:
- +50mm: Recirculated to secondary crusher
- 20–50mm: Conveyed to tertiary crushing
- -20mm: Directly fed to stockpiles for transport

4. nghiền cấp ba: Máy nghiền tác động

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. Hệ thống xử lý vật liệu
Corrosion-resistant belt conveyors with dust suppression systems transport material between stages. Ổ đĩa tần số thay đổi (VFD) enable energy-efficient speed adjustments based on feed rates.
