175 TPH Mobile Limestone Crushing Plant In Zambia

Client Background

The client is a leading construction and mining company in Zambia, specializing in aggregate production for infrastructure development. With a growing demand for high-quality limestone aggregates, they sought a mobile, efficient, and reliable crushing solution that could handle 175 tons per hour (TPH) with minimal downtime.

Project Overview

• Material: Limestone
• Required Capacity: 175 TPH
• Location: Zambia
• Solution: NK Series Mobile Crushing Station

To meet the client’s demands, Liming Heavy Industry recommended a customized mobile crushing plant with high productivity, ease of transportation, and low operating costs.

Challenges

1. High Production Demand – The client needed a crushing solution with stable output of 175TPH.
2. Mobility & Flexibility – Since mining sites often change, a mobile station was essential for quick relocation.
3. Dust & Noise Control – Compliance with environmental regulations required low dust and noise emissions.
4. Hard Limestone Crushing – The material’s abrasiveness demanded wear-resistant crushers for longevity.

Solution: Liming Heavy Industry’s Customized Mobile Crushing Line

After evaluating the client’s requirements, we engineered a high-efficiency, semi-mobile crushing plant consisting of:

1. NK Series Mobile Jaw Crusher – Primary Crushing (NK80-2)

• Model: NK80-2 (Equipped with PE600×900 Jaw Crusher)
• Function: Primary crushing of raw limestone (≤500mm → ≤150mm).
• Advantages:
  • High crushing ratio & deep crushing cavity for hard limestone.
  • Hydraulic adjustment for easy maintenance.
  • Diesel-electric dual-power system for fuel efficiency.

2. NK Series Mobile Impact Crusher – Secondary Crushing (NK200-2S)

• Model: NK200-2S (Equipped with PFW1315 Impact Crusher)
• Function: Secondary crushing (≤150mm → ≤30mm).
• Advantages:
  • Superior cubical-shaped aggregate output.
  • Hydraulic opening system for quick maintenance.
  • Environmentally sealed design to reduce dust.

3. S5X Vibrating Screen – Efficient Screening (S5X1860-3)

• Model: S5X1860-3
• Function: Screening and grading aggregates to meet different construction standards (0-5mm, 5-10mm, 10-20mm, 20-30mm).
• Advantages:
  • Multi-layer screening with high accuracy.
  • Rubber spring damping system for lower noise & vibration.

Technical Highlights:

• Intelligent Control System – Remote monitoring & PLC automation for optimal performance.
• Hybrid Power Mode – Reduced fuel consumption & eco-friendly operation.
• Quick Deployment – Modular design allows fast on-site assembly (<24 hours).

Project Results

• Production Capacity Achieved: 175-190 TPH, exceeding expectations.
• Finished Product Quality: Well-graded, cubical aggregates ideal for concrete and road construction.
• Mobility & Downtime Reduction: Quick site transitions reduced idle time by 40%.
• Environmental Compliance: Dust suppression system met Zambia’s mining regulations.
