Hard Copper Ore (Mohs Hardness 7.5)
600 - 800 TPH
Running Stably
Tailored for the extreme cold climates of Central Asia and the characteristics of high-hardness copper ore, Liming Heavy Industry's engineering expert team designed a highly redundant and stable "Primary Jaw Crushing + Secondary Medium Cone Crushing + Tertiary Fine Cone Crushing + High-frequency Screening" three-stage closed-circuit crushing production system. Adhering to the advanced processing principle of maximizing crushing efficiency, the final particle size entering the next beneficiation stage is strictly controlled below 12mm, significantly reducing the subsequent energy consumption of the entire plant.
Large run-of-mine ore (blasted size ≤1000mm) is efficiently processed by the PEW European Type Jaw Crusher with a large discharge opening, rapidly reducing the material size.
The primary crushed material enters the HST Single Cylinder Hydraulic Cone Crusher. Utilizing its constant discharge opening and powerful inter-particle laminating crushing force, it achieves high-capacity conversion of the middle-stage materials.
The HPT Multi-cylinder Hydraulic Cone Crusher is introduced as the ultimate fine crusher. Materials that do not meet the size requirements are classified by the S5X high-frequency vibrating screen and returned for re-crushing, ensuring zero coarse material overflow.
All core machines across the entire line feature Liming Heavy Industry's high-end heavy-duty mining equipment. High-strength cast steel bearing housings and automated hydraulic systems guarantee long-term, durable operation.
| Processing Stage | Core Equipment | Model & Specification | Quantity / Configuration | Core Functional Role |
|---|---|---|---|---|
| Primary Crushing | European Type Jaw Crusher | PEW1100 | 1 Unit | Primary hard rock breaker, optimizing feeding structure |
| Secondary Crushing | Single Cylinder Hydraulic Cone Crusher | HST315 / S2 | 1 Unit | High-throughput medium crusher, providing stable intermediate ore flow |
| Tertiary Fine Crushing | Multi-cylinder High-efficiency Cone Crusher | HPT500 / F | 2 Units | Large laminating crushing ratio, achieving ultra-fine crushing to maximize downstream efficiency |
| Product Screening | High-frequency Heavy-duty Vibrating Screen | S5X2460-3 | 4 Units | Multi-deck linked operation, ensuring 0-12mm closed-circuit loop |
On-site operational highlights: Even in extreme climates, the intelligent control system of the equipment ensures safe, reliable, and continuous production.
"We highly appreciate the complete EPC solution provided by Liming Heavy Industry. In the extreme cold and dusty environment of Karaganda, the overall operation rate of this system exceeds 92%. The fully automated hydraulic cavity clearing and discharge adjustment functions not only greatly improve operational safety but also helped us reduce on-site maintenance labor by nearly 40%."
Whether it is hard metallic ore, highly abrasive granite, or ultra-large capacity requirements, Liming Heavy Industry's global backbone engineering team will provide a customized 3D process layout and investment budget estimation within 24 hours.
