200 TPH Lead-Zinc Ore Crushing Solution in Afghanistan

Client Overview

A mining company in Afghanistan sought a reliable partner to process lead-zinc ore at 200 tons per hour (TPH) for their expanding operations. Harsh terrain and limited infrastructure demanded durable, high-efficiency equipment.

Project Overview

Location: Afghanistan
Material: Lead-Zinc Ore (compressive strength: 120-150 MPa)
Feed Size: ≤750mm
Output Size: 0-30mm (adjustable)
Capacity: 200 TPH
Challenge: Abrasive ore, intermittent power supply, and need for minimal downtime.

Challenges

1. Hard Ore Characteristics: Lead-zinc ore’s abrasiveness required wear-resistant crushers.
2. Throughput Demand: Consistent 200 TPH output under extreme conditions.
3. Infrastructure Limitations: Adaptable equipment for limited grid power and rough terrain.

Solution: Customized Crushing Line by Liming

1. Primary Crushing: PEW Series Jaw Crusher (PEW1100)
   • Role: Coarse crushing to reduce 750mm ore to ~200mm.
   • Advantage: Deep crushing chamber + hydraulic adjustment for abrasive ore.
2. Secondary Crushing: HPT Multi-Cylinder Hydraulic Cone Crusher (HPT300)
   • Role: Further crush to 30mm with high cubicity.
   • Advantage: Laminated crushing + automatic control for stable output.
3. Supporting Equipment:
   • Vibrating Feeder (GZD1500×6000): Uniform feeding to prevent blockage.
   • Belt Conveyor (B6X Series): Dust-proof & impact-resistant for long-distance transport.

Technical Highlights

• Energy Efficiency: HPT crusher’s hydraulic system reduces power consumption by 15%.
• Smart Control: PLC system monitors performance and adjusts settings in real time.
• Low Maintenance: PEW jaw crusher’s modular design simplifies wear-part replacement.

Results

• Output: Steady 200-210 TPH, exceeding the target.
• Downtime Reduction: 40% fewer stoppages vs. the client’s old setup.
• Cost Savings: 30% lower spare parts consumption due to wear-resistant materials.
