400 TPH Construction Waste Recycling Line in Qatar

Client Overview

Our client is a leading construction and demolition waste recycling company in Qatar, focusing on sustainable solutions to reuse concrete waste and construction debris. They needed a high-efficiency 400 TPH sand and gravel production line to process mixed demolition waste into reusable aggregates for new construction projects.

Project Background

Qatar’s rapid infrastructure development has increased construction waste disposal challenges. The client required a turnkey crushing and screening solution to convert waste concrete and construction debris into high-quality 0-5mm sand, 5-20mm gravel, and 20-40mm coarse aggregates for road base and concrete production.

Challenges

1. Abrading Materials: Concrete waste and rebar from demolition can damage crushers.
2. High-Volume Processing: Requires 400 TPH capacity and consistent output.
3. End Product Quality: Recycled sand and gravel must meet Qatar’s strict construction standards.
4. Space Constraints: The plant needed a compact, mobile-friendly layout.

Solution by Liming Heavy Industry

We designed a fixed crushing and screening plant with multiple-stage crushing to ensure maximum efficiency.

Equipment & Configuration

1. Feeding & Pre-Screening
   • GZD Vibrating Feeder: Stable feeding to avoid blockages.
   • 2YKN Vibrating Screen: Removes soil and small impurities before crushing.
2. Primary Crushing (Coarse Aggregates)
   • PEW Jaw Crusher (PEW1100): Handles large concrete chunks with high wear resistance.
     • Advantage: Deep crushing cavity for demolition waste; high output up to 400 TPH.
3. Secondary Crushing (Medium-Size Aggregates)
   • PFW Impact Crusher (PFW1315III): Breaks down reinforced concrete with hydraulic adjustment for easy maintenance.
     • Advantage: Strong impact force to crush steel-reinforced debris.
4. Tertiary Crushing & Sand Making (Fine Aggregates & Sand)
   • VSI6X Sand Maker (VSI6X1263): Produces high-quality 0-5mm manufactured sand for concrete mixing.
     • Advantage: “Rock-on-Rock” & “Rock-on-Iron” crushing modes adapt to different material hardness.
5. Screening & Grading
   • 3YKN Vibrating Screen: Separates aggregates into 0-5mm, 5-20mm, and 20-40mm fractions.
   • Belt Conveyors: Custom lengths for seamless material transfer.

Technical Highlights

• Smart Control System: Remote monitoring & automatic adjustment.
• Wear-Resistant Parts: Extended service life in abrasive conditions.
• Dust Suppression: Water spray system for eco-friendly operation.

Project Results

• Capacity: 400 TPH continuous operation, meeting Qatar’s demand.
• Product Quality: High-quality sand and gravel meet ASTM and BS standards.
• Cost Savings: Reduced landfill expenses & 30% lower operating costs vs. new quarrying.

Client Feedback

“Liming’s construction waste recycling plant has exceeded our expectations. The VSI6X Sand Maker produces perfect sand for concrete, and the PFW Impact Crusher handles steel-reinforced waste smoothly. Their team’s technical support was outstanding!”
