Project Overview
In Hunan Province, a large-scale Construction Waste Sorting and Recycling Plant built by Zhongyi Machinery has been successfully installed and commissioned. The system is designed to process construction waste, renovation debris, and mixed solid waste, with a daily processing capacity of 1,000 cubic meters.
Through an integrated process involving crushing, screening, air classification, and material recovery, the project transforms construction and renovation waste into reusable resources, thereby supporting local green development initiatives. Zhongyi Machinery’s engineering team conducted on-site commissioning at the client’s facility to ensure full system integration and stable operation prior to official production.

Customer Requirements
With rapid urban redevelopment in the region, the client was facing increasing pressure from large volumes of construction and demolition waste and renovation debris. The main challenges included:
- Mixed waste streams containing bricks, concrete, wood, plastics, metals, and soil
- Low efficiency of traditional manual sorting methods
- High transportation and landfill disposal costs
- Difficulty in producing consistent-quality recycled aggregates
- Lack of an automated and scalable waste recycling system
The client required a complete C&D waste processing solution capable of stable operation, intelligent sorting, and high resource recovery rates.
Zhongyi Machinery Solution
Based on site conditions and material characteristics, Zhongyi Machinery designed a fully integrated Construction Waste Sorting and Recycling System featuring modular equipment layout and intelligent control technology. The solution focuses on:
- Stable feeding and pre-treatment of mixed waste
- Multi-stage crushing for efficient size reduction
- High-precision screening for material classification
- Air separation for light and heavy fraction sorting
- Metal recovery and recyclable material collection
- Centralized intelligent control and remote monitoring system
This configuration ensures that construction waste is efficiently converted into reusable materials such as recycled aggregates, metals, and combustible fractions.
System Equipment Composition and Functions
- Heavy-Duty Apron Feeder: Provides stable and continuous feeding of bulky construction and renovation waste, preventing material blockage and ensuring smooth downstream processing.
- Solid Waste Crusher: Performs primary and secondary crushing of concrete blocks, bricks, and demolition waste, reducing materials into uniform particles suitable for recycling applications.
- Bar-Type Flip-Flow Screen: Handles high-moisture and sticky materials efficiently, improving screening accuracy and increasing throughput compared to traditional vibrating screens.
- Ballistic Separator (Bounce Screen): Separates light materials such as wood, plastics, and paper from heavy fractions like concrete and stone with high precision and stable performance.
- Vertical Negative Pressure Air Separator (2 Units): Uses controlled airflow and dust suppression technology to separate lightweight materials such as foam, film, and combustible waste, significantly improving resource recovery efficiency.
- Trommel Screening System: Pre-screens mixed waste materials, removing fine particles and improving the efficiency of downstream sorting and crushing systems.
- Magnetic Separator: Automatically extracts ferrous metals from mixed waste streams, ensuring complete metal recovery and protecting equipment from damage.
