100 TPH Quartz Stone Crushing Project in Vietnam

Client Overview

A leading Vietnamese construction materials supplier sought to establish a high-capacity quartz stone processing line to produce premium-quality sand and aggregates for local infrastructure projects.

Project Overview

• Location: Vietnam
• Material: Quartz Stone (Hardness: 7 Mohs)
• Capacity: 100 tons per hour
• Output: 0-5mm sand, 5-10mm, 10-20mm, and 20-30mm aggregates
• Application: Ready-mix concrete and high-grade construction sand

Challenges

1. High Abrasiveness: Quartz’s hardness demanded wear-resistant equipment.
2. Output Quality: Required uniformly shaped sand for commercial concrete.
3. Space Constraints: Compact layout for limited quarry area.

Liming Heavy Industry’s Solution

1. Equipment Configuration

• Primary Crushing: C6X Jaw Crusher
  • Model: C6X145
  • Role: Coarse crushing of raw quartz (≤650mm) to ≤150mm.
  • Advantage: Robust structure, energy-efficient motor.
• Secondary Crushing: HPT Multi-Cylinder Hydraulic Cone Crusher
  • Model: HPT300
  • Role: Medium/fine crushing to ≤40mm.
  • Advantage: Lamination crushing, 30% longer liner lifespan.
• Tertiary Sand Making: VSI6X Sand Maker
  • Model: VSI6X1263
  • Role: Producing 0–5mm high-purity sand with ≤3% needle content.
  • Advantage: Optimized impeller design, low noise (<75dB).
• Screening: S5X Vibrating Screen
  • Model: S5X2460-2
  • Role: Precise particle classification.
  • Advantage: Multi-layer screening, plug-resistant mats.

2. Flowchart

Quartz → C6X Jaw Crusher → HPT Cone Crusher → VSI6X Sand Maker → S5X Screen → Finished Products

Technical Highlights

• Low Wear Costs: HPT300’s alloy mantle/VSI6X’s tungsten carbide tips reduced wear part replacement frequency by 40%.
• Automation: PLC system enabled real-time monitoring of production data.
• Dust Control: Integrated pulse dust collector (compliance with Vietnam’s environmental standards).

Results

• Capacity Achieved: 105TPH (exceeding target by 5%).
• Sand Quality: Cubical particles, fineness modulus of 2.8–3.0, ideal for concrete.
• ROI: Payback period of 10 months due to low operational costs.

Client Feedback

“Liming’s VSI6X and HPT300 exceeded our expectations. The sand meets European EN-12620 standards, and their engineers provided excellent EPC support.” — Mr. Nguyen, Plant Manager
