300 TPH Iron Ore Crushing Plant in South Africa

Client Profile

1. Location: South Africa
2. Industry: Mining
3. Material: Iron Ore (Mohs hardness: 5.5–6.5)
4. Demand: Stable output of 300 tons per hour with high durability for abrasive ore.

Project Overview

A South African mining company sought a reliable crushing solution to process iron ore into 0–25mm aggregates for pelletizing. Key requirements included high capacity (300 TPH), wear resistance, and low downtime.

Challenges

1. Material Abrasiveness: Iron ore’s hardness caused rapid wear in conventional crushers.
2. Throughput Demand: Required consistent 300 TPH output without bottlenecks.
3. Site Conditions: Limited maintenance infrastructure in remote mining area.

Liming’s Solution: Customized 300 TPH Crushing Line

Equipment Configuration & Advantages

1. Primary Crushing – PE1200×1500 Jaw Crusher
   • Role: Coarse crushing of raw iron ore (≤750mm) to ≤200mm.
   • Advantages:
     • High crushing ratio (6:1) and deep chamber design for iron ore.
     • Manganese steel jaws resist abrasion, 30% longer lifespan than competitors.
2. Secondary Crushing – HST315 Single-Cylinder Hydraulic Cone Crusher
   • Role: Further crush 200mm feed to ≤25mm.
   • Advantages:
     • Fully hydraulic adjustment ensures precise discharge size control.
     • Labyrinth seal system prevents dust ingress, reducing bearing wear.
3. Auxiliary Equipment:
   • ZSW600×130 Vibrating Feeder: Evenly feeds material to prevent overload.
   • 3YK3072 Vibrating Screen: Separates fines (<10mm) for pelletizing.
   • Belt Conveyors: Reinforced rubber layers resist iron ore abrasion.

Technical Highlights

• Automation System: PLC control enables remote monitoring of crusher load and oil temperature.
• Dust Suppression: Water sprays at transfer points comply with South African environmental standards.
• Energy Savings: HST315’s hydraulic system reduces power consumption by 15% vs. spring cone crushers.

Project Results

• Achieved Capacity: 320 TPH (exceeding the 300 TPH target).
• Product Size: 85% of output at 10–25mm (ideal for pelletizing).
• Downtime Reduction: <5% due to wear-resistant liners and easy maintenance access.

Client Feedback
