Qunfeng Heavy Industry's construction waste treatment system can process construction waste into concrete aggregate, raw materials for new wall materials, road base filling accessories, sand and stone aggregate for high-speed railway construction and other recycled aggregate, which can be recycled locally to reduce transportation costs and avoid secondary pollution.
In modern construction projects, handling large amounts of debris is always a challenge. Our construction waste treatment system tackles this efficiently, turning rubble, concrete, and asphalt into reusable materials. Inspired by techniques used in mining machines and industrial mining equipment, our system is designed to handle heavy-duty crushing, screening, and sorting with precision.
Construction Waste Treatment System efficiently handles debris from demolition, turning concrete, bricks, plastics, and metals into reusable materials. Inspired by mining machine techniques, our system combines crushing, screening, and advanced separation technologies to maximize material recovery.
These systems separate construction waste by particle size, ensuring efficient downstream processing:
Trommel Screen: otating cylindrical screen separates materials by size.
Vibratory Screen / Vibrating Screen: Uses vibration to separate fine and medium fractions.
Disc Screen: Separates materials by size and shape, commonly used for cardboard and paper.
Star Screen: Rotating star-shaped elements separate light and flat materials from heavier ones.
Grizzly Screen: Heavy-duty bars remove oversized materials before further processing.
Airflow and density separation are applied for lightweight and heavy material segregation:
Air Separator / Air Classifier: Separates materials using airflow based on density and aerodynamic properties.
Wind Sifter: Blows lighter materials like film, plastic, and paper away from heavier fractions.
Zig-Zag Air Separator: Zig-zag channels improve separation efficiency of light and heavy materials.
Float-Sink Separator: Uses water or other liquids to separate lighter materials that float from heavier ones that sink.
These units extract metals from construction waste streams, supporting recycling:
Magnetic Separator: Removes ferrous metals such as iron and steel.
Overband Magnet: Conveyor-mounted magnet to extract black metals from moving waste.
Drum Magnet: Rotating drum continuously separates ferrous metals.
Eddy Current Separator (ECS): Separates non-ferrous metals like aluminum and copper using induced currents.
Advanced sensors identify and sort materials based on color, composition, or density:
Optical Sorter: Uses NIR, VIS, or laser sensors to identify and separate materials by type or color.
Near-Infrared (NIR) Sorter: Detects plastics, paper, and organic materials using near-infrared spectroscopy.
Color Sorter: Separates glass and plastics based on color.
X-ray Transmission (XRT) Sorter – Detects density differences for heavy materials or minerals.
Manual sorting stations and ergonomic cabins complement automated systems:
Manual Sorting Station: Operators manually remove specific materials from conveyor belts.
Sorting Cabin: Enclosed area with dust control and ergonomic features for manual sorting.
Shredding prepares construction waste for effective separation:
Shredder: Reduces waste size to improve downstream separation efficiency.
Primary Shredder: Coarse size reduction at the beginning of the process.
Secondary Shredder: Provides finer shredding after initial separation.
Bag Opener: Opens plastic waste bags without excessive shredding of contents.
These auxiliary systems ensure smooth material flow throughout the plant:
Belt Conveyor: Transports waste materials between separation units.
Chain Conveyor: Heavy-duty conveyors for bulky or abrasive waste.
Screw Conveyor / Auger: Moves fine or semi-solid materials using a rotating screw.
Feeder: Controls material flow into separation equipment.
Powerful Crushing and Screening: Borrowing principles from mining machines and crushing equipment, our system processes mixed construction waste quickly, separating concrete, bricks, and metals for reuse.
Smart Material Recovery: Similar to how ore processing machines in mining recover valuable minerals, our system recovers aggregates and metals from construction waste, reducing landfill needs and improving cost efficiency.
Flexible and Reliable Design: Built on modular designs common in heavy-duty mining machinery, the system can be adapted to urban sites or large-scale demolition projects, offering stable and long-lasting performance.
Eco-Friendly Operation: With dust and noise control technologies inspired by excavation machines and mining machine engineering, the system minimizes environmental impact while keeping the site safe and compliant with regulations.
From city demolition sites to industrial redevelopment projects, this treatment system turns construction waste into a valuable resource, using mining machine techniques and material recovery equipment to make every step more efficient.
