200 TPH River Stone Crushing Plant in Nepal

Client Background

Our client, a leading construction and mining company in Nepal, specializes in high-quality aggregates production. With increasing infrastructure and road construction projects, they needed a reliable crushing plant to process river stone into various sizes of sand and gravel for concrete and asphalt.

Project Overview

• Location: Nepal
• Material: River stone (hardness ~150-200MPa)
• Required Output: 200 tons per hour (TPH)
• Final Products:
  • 0-5mm (sand for concrete)
  • 5-20mm (aggregate for road base)
  • 20-40mm (larger gravel for construction)

Key Challenges

• High abrasiveness of river stone affecting equipment durability.
• Need for precise particle shape for high-grade concrete production.
• Space constraints at the quarry site.
• Low power supply stability in remote regions.

Solution by Liming Heavy Industry

To meet the client’s requirements, Liming Heavy Industry designed a 200TPH river stone crushing and screening plant with the following configuration:

1. Primary Crushing – PE900x1200 Jaw Crusher

• Role: Coarse crushing of large river stones (≤700mm).
• Advantages:
  • Deep crushing cavity for higher capacity.
  • High wear resistance with Mn18Cr2 jaw plates.
  • Stable and energy-efficient operation.

2. Secondary Crushing – HPT300 Hydraulic Cone Crusher

• Role: Intermediate crushing to produce well-shaped 5-40mm aggregates.
• Advantages:
  • Multi-cylinder hydraulic system for fine particle adjustment.
  • Laminated crushing principle for better particle shape.
  • Low dust and low maintenance structure.

3. Sand Making – VSI6X1150 Impact Crusher

• Role: Produces high-quality 0-5mm sand with excellent gradation.
• Advantages:
  • Deep rotor design for higher sand yield.
  • Low iron contamination for premium concrete sand.
  • Energy-saving motor reduces operating costs.

4. Screening & Conveying – S5X2460-3 Vibrating Screen & B6X Belt Conveyor

• Role: Classifies final aggregates into different sizes.
• Advantages:
  • Multi-layer screening ensures precise separation.
  • Dust-proof and noise-reducing design.

Technical Highlights

• Automatic Control System – Ensures smooth, stable production.
• Dust Suppression Technology – Eco-friendly and complies with Nepal’s environmental regulations.
• Easy Maintenance Design – Reduces downtime.

Project Results

Production Capacity: Exceeded target at 210-220 TPH.
Final Product Quality:

• Cubic-shaped aggregates for asphalt and concrete.
• Low powder content for high-grade sand.
• Operational Stability: 98% uptime even in tough conditions.
