2000m³/Day Construction and Renovation Waste Recycling Plant Project in Zhejiang, China

Project Overview

Customer Requirements and Project Challenges

With rapid urban development and increasing renovation activities, the amount of construction and decoration waste has continued to grow. Unlike single-type waste streams, renovation waste usually contains a complex mixture of concrete blocks, bricks, tiles, steel, wood, plastic and other impurities, making efficient recycling and material separation more challenging.

The customer required a large-scale recycling system capable of continuously processing mixed construction and renovation waste while maintaining stable operation and producing high-quality recycled products. Traditional manual sorting methods could not meet the required processing capacity, while direct landfill disposal would lead to resource waste and increased environmental pressure.
The main challenges included:

• Processing large volumes of mixed construction and renovation waste
• Separating materials with different sizes, weights and physical characteristics
• Removing impurities to improve the quality of recycled aggregates
• Ensuring stable production with reduced manual sorting requirements

The client required a complete construction waste recycling solution to process mixed construction waste containing concrete, bricks, wood, plastic and metals. The system needed to achieve efficient material classification, stable high-capacity operation and the production of reusable recycled aggregates and recovered resources for further applications.

Zhongyi Construction Waste Recycling Solution

Based on the characteristics of the incoming materials and the customer’s production requirements, Zhongyi Machinery designed a complete construction waste recycling solution integrating feeding, screening, crushing and separation technologies. The system is designed to efficiently process mixed construction and renovation waste, maximize material recovery and produce high-quality recycled products.

The complete recycling process includes:

• Feeding System: Provides stable and continuous feeding for mixed construction waste.
• Pre-screening: Removes smaller-size materials and unsuitable fractions to improve the efficiency of downstream processing.
• Primary Crushing: Reduces large materials such as concrete blocks and bricks into suitable sizes for further processing.
• Multi-stage Screening: Classifies materials according to particle size and physical characteristics to improve separation efficiency.
• Magnetic Separation: Recovers ferrous metals such as steel bars and iron pieces from the waste stream.
• Air Separation: Removes lightweight impurities including plastic, wood, paper and foam materials to improve recycled product quality.
• Secondary Crushing: Further processes selected materials into required particle sizes for recycled aggregate production.
• Recycled Product Output: Produces reusable recycled aggregates and recovered resources for construction applications.

Through this integrated recycling process, the system improves resource recovery efficiency, reduces waste disposal pressure and provides a reliable solution for construction waste recycling and reuse.

Main Equipment Configuration

1. Apron Conveyor

Function: The Apron Conveyor provides stable and continuous feeding for mixed construction and renovation waste. It is designed to handle large and irregular materials, ensuring a uniform material flow into the recycling system and improving the stability of the entire production line.

2. Jaw Crusher

Function: The Jaw Crusher performs primary crushing of large construction waste materials such as concrete blocks and bricks. It reduces oversized materials into suitable particle sizes, creating better conditions for subsequent screening and separation processes.

3. Flip Flow Screen

Function: The Flip Flow Screen is used for efficient screening of mixed construction and renovation waste, especially materials with high moisture content and sticky characteristics. It separates materials by particle size and improves the efficiency of downstream recycling processes.

4. Magnetic Separator

Function: The Magnetic Separator recovers ferrous metals such as steel bars, iron pieces and other magnetic materials from the waste stream. It improves resource recovery efficiency while increasing the value of recovered materials.

5. Horizontal Negative Pressure Air Separator

Function: The Horizontal Negative Pressure Air Separator removes lightweight impurities such as plastic, wood and paper through airflow separation technology. It improves the purity of recycled aggregates and enhances the overall quality of recovered materials.

Construction Waste Recycling Process

The mixed construction and renovation waste is first delivered into the recycling system for uniform feeding and preliminary screening. Large materials such as concrete blocks, bricks and other hard waste are then processed through crushing and multi-stage screening to achieve suitable particle sizes for further separation and recycled aggregate production.

After screening and crushing, the processed materials enter the separation stage, where ferrous metals and lightweight impurities such as plastic, wood, paper and foam are removed. Through the integrated crushing, screening and separation process, the plant improves material recovery efficiency and produces reusable recycled aggregates, recovered metals and other recyclable materials.
