Project Location: Hebei Province, China

Commission Date: August 2026

Target Feedstock: Mixed Construction & Demolition (C&D) Waste, Interior Renovation Debris

Core Processing Capability: Multi-fraction mechanical separation (Aggregates, Fine Soil, Ferrous Metals, Light RDF Plastics)

The Operational Challenge

Urban renovation and demolition projects generate highly heterogenous waste streams comprising heavy concrete rubble, brick fragments, soil, rebar, packaging plastics, and textiles. Processing this mixed feedstock poses significant operational hurdles:

• High Equipment Wear: Directly crushing unsorted debris causes severe wear on crusher blow bars and jaws due to trapped rebar and tramp metal.

• Fraction Contamination: Light organics (plastics, woven bags, foam) ruin the structural quality of recycled concrete aggregates if not separated prior to crushing.

• Dust & Environmental Hazards: Processing dry, fine construction soil requires enclosed containment and automated material transport to maintain environmental compliance.

Onsite Process Architecture & Equipment Integration

Guoxin Group engineered a fully enclosed, automated mechanical sorting line tailored to Hebei’s high-throughput C&D waste requirements.

1. Heavy-Duty Reception & Incline Conveying: Wheel loaders and excavators feed raw, mixed renovation waste into an underground receiving hopper. Heavy-duty incline belt conveyors continuously transfer material into the enclosed processing hall.
2. Magnetic Metal Extraction: An industrial overband magnetic separator positioned above the main conveyor line continuously pulls out rebar, wire mesh, and iron hardware, discharging clean ferrous scrap into a dedicated container.
3. Dynamic Air & Screen Classification (GX-75-2200 Unit): Material enters Guoxin’s high-efficiency GX-75-2200 separator. Controlled air currents combined with mechanical vibration separate light materials from dense fractions.
4. Multi-Stream Fractionation & Discharge:

• • Heavy Stone & Concrete Stream: Clean concrete rubble and brick debris are discharged onto high-capacity aggregate stockpiles, ready for secondary crushing into road base material.

  • Fine Soil & Inert Stream: Fine earth and sand fractions are isolated and conveyed onto separate stockpiles for backfill and land reclamation.

  • Light Organic Stream: Film plastics, woven bags, and wood residue are blown into high-density RDF piles for energy recovery.

Key Performance Indicators & Results

Commercial Value Delivered

By transforming raw demolition waste into homogenous, market-ready resource streams, this facility turns a municipal waste management challenge into a profitable recycling operation. The recovered concrete aggregates serve local infrastructure projects, while the extracted light fraction provides high-calorific feedstock for industrial waste-to-energy conversion.
