Project Overview
With increasing urban renewal and building renovation, construction and renovation waste has become a growing challenge for cities. Mixed materials such as concrete, bricks, soil, wood, plastics, foam, and metals are difficult to handle efficiently through conventional disposal methods.
To improve resource recovery, the customer installed a complete Zhongyi Machinery renovation waste recycling line designed for automated crushing, screening, separation, and material recovery.
Feed Material: Mixed construction and renovation waste, including concrete, bricks, soil, wood, plastics, foam, and metals
Service: Site assessment, process design, equipment installation, commissioning, and production support
150-200 t/h
Processing Capacity
Customer Requirements and Project Challenges
The customer needed a continuous processing solution for mixed construction and renovation waste, where large and irregular materials, lightweight fractions, and metal contaminants made conventional sorting difficult. The system had to maintain stable throughput while improving material separation and recovery quality.
Main project challenges:
- Capacity: 150–200 t/h continuous processing
- Mixed feed: Concrete, bricks, soil, wood, plastics, foam, and metals
- Efficient separation: Recover aggregates, fine materials, metals, and lightweight fractions
- Stable conveying: Handle large and irregular incoming materials
- Environmental control: Reduce dust and noise during operation
- Project support: Process design, installation, commissioning, and startup assistance
Zhongyi Construction & Renovation Waste Recycling Solution
Zhongyi Machinery developed a complete recycling line tailored to the characteristics of mixed construction and renovation waste. The process combines heavy-duty feeding, crushing, screening, air separation, magnetic separation, and conveying to handle different material sizes and densities while separating reusable fractions from lightweight and unwanted materials.
The system uses flip-flop screening technology to improve screening performance for mixed and difficult materials. Negative-pressure and hanging air separators remove lightweight materials such as plastic film, foam, and wood, while magnetic separation recovers ferrous metals. The conveying and feeding equipment are designed to maintain stable material flow throughout the process.
The final solution enables the customer to recover recycled aggregates, fine materials, ferrous metals, wood, and lightweight fractions from renovation waste. Zhongyi Machinery provided the complete engineering service, including process design, equipment supply, installation, commissioning, and production support, delivering a practical recycling solution based on the actual site and material conditions.
Main Equipment Configuration
Zhongyi Machinery configured the recycling line around the characteristics of mixed construction and renovation waste, combining crushing, screening, air separation, and conveying to achieve effective separation of heavy, fine, and lightweight fractions. The key equipment and their roles are as follows:
- Double-Deck Flip-Flop Screen: Performs multi-stage screening of mixed waste and separates fine materials from larger fractions while reducing the risk of screen blockage.
- Heavy-Duty Flip-Flop Screen: Handles larger and more irregular materials, providing stable screening under demanding working conditions.
- Negative-Pressure Air Separator: Removes lightweight contaminants such as plastic film, foam, and wood from heavier materials through controlled airflow.
- Hanging Air Separator: Provides additional lightweight-material separation to improve the cleanliness of recovered aggregates.
- Apron Conveyor: Handles heavy, large, and irregular construction waste with stable, continuous conveying.
- Crusher: Reduces oversized concrete, bricks, and other hard materials to a suitable size for downstream screening and separation.
Construction and Renovation Waste Recycling Process
The renovation waste is first fed into the system through the apron conveyor, where a crusher reduces oversized concrete, bricks, and other hard materials to a suitable size. The processed material then enters the double-deck flip-flop screen and flip-flop screen for size separation. The classified material passes through the negative-pressure air separator and hanging air separator, which remove lightweight materials such as foam, plastic film, and wood, while heavier materials continue through the recycling process.
The separated materials are then conveyed to their respective discharge points for collection and further processing. Through this combination of crushing, screening, air separation, and conveying, the system effectively separates mixed renovation waste into different material fractions while maintaining a continuous and stable recycling process.

Advantages
The construction and renovation waste recycling solution is designed to convert mixed waste into reusable materials through a continuous crushing, screening, and separation process. By combining heavy-duty feeding, flip-flop screening, air separation, and conveying, the system separates aggregates, fines, metals, wood, and lightweight materials while maintaining stable operation under demanding feed conditions.
- Integrated Recycling Process: Combines crushing, screening, air separation, and conveying into a continuous processing system for mixed construction and renovation waste.
- Effective Lightweight Material Removal: Dual air-separation stages help remove foam, plastic film, wood, and other lightweight contaminants from heavier materials.
- Stable Heavy-Duty Operation: The apron conveyor and screening equipment are designed to handle large, irregular, and mixed waste materials with stable feeding and conveying.
- Improved Material Quality: Multi-stage screening and separation help improve the cleanliness of recovered aggregates and other recyclable fractions.
- Resource Recovery: Separates renovation waste into reusable fractions such as recycled aggregates, fine materials, metals, wood, and lightweight materials, reducing disposal volumes.
- Project-Based Engineering: Zhongyi Machinery provides process design, equipment configuration, installation, commissioning, and production support according to actual material and site conditions.
Project Results
The recycling line successfully completed its initial commissioning and has maintained stable continuous operation with a low equipment failure rate. The combined screening and air separation process effectively sorts and purifies the renovation waste, producing reusable materials including recycled aggregates, fine sand, reclaimed wood, ferrous metals, and lightweight plastics. The recovered materials meet the required reuse standards and can be further used in building material production and infrastructure projects, significantly reducing the volume of waste sent to landfill.
The entire line operates with effective environmental controls, including low-dust and low-noise performance, in line with local environmental requirements. By reducing waste disposal costs and generating additional revenue from recovered materials, the project has delivered both environmental and economic benefits and has been highly recognized by the customer as a practical example of renovation waste recycling in the region.
