Why Choose Guoxin Machinery?

Made in China, Global Projects.  We professionally design and build integrated waste recycling and sorting systems, combining crushing, shredding,  screening, sorting, washing, dewatering, and dust removal into a highly efficient, modular process. Our systems offer multiple drive and layout options and can be deeply customized to your specific material composition and output targets, aiming to maximize resource recovery rates while significantly reducing the cost per ton of processing.

China Waste Sorting Equipment

• OEM/ODM Customization: Full customization is supported, from equipment painting, module combination, electrical configuration, to control interface language and branding.
• Rapid Deployment: Core units are pre-assembled and pre-wired; using skid-mounted modules and quick-connect design, the typical installation and commissioning cycle can be shortened to 10-20 days.
•  Stable and Efficient Output: Ensuring high-purity recyclables (such as plastics and metals), stable RDF (waste-derived fuel) quality, and clean aggregates.
• Full-Process Service: Provides on-site installation guidance, commissioning, operation training, and complete export compliance documentation (CE/ISO certification).

I. Typical Process Flow

•  Feeding and Pre-treatment — Plate feeder + coarse screen, evenly feeds and removes oversized objects.
• Crushing and Homogenization — Twin-shaft shear shredder or low-speed high-torque crusher, breaks up bags(bag opener machine) and homogenizes the size of mixed waste.
•  Screening and Grading — Drum trommel screen or bouncing screen, initially separates materials by size (e.g., <80mm organic matter, >80mm combustibles and recyclables).
•  Magnetic Separation and Eddy Current Separation — Suspended magnetic separator recovers ferrous metals; eddy current separator efficiently separates non-ferrous metals.
•  Fine Separation — Near-infrared (NIR) optical separator, accurately identifies and sorts different types of plastics (PET, PP, PE, etc.) and impurities.
•  Air Classification and Gravity Separation — Air classifiers separate light combustibles (RDF raw materials); air density separators further purify the material.
•  Washing and Dewatering (Optional) — For plastic fragments, equipped with a friction washer, rinsing tank, and dewatering machine to produce clean flakes.
•  Dust Removal and Deodorization — A fully enclosed conveyor system combined with a pulse dust collector; biological filters or chemical scrubbing towers treat waste gas.
•  Intelligent Control — A PLC-based central control system integrating material flow monitoring, equipment interlocking, and remote data monitoring.

II. System Configuration Example

1. Mixed Municipal Solid Waste Resource Utilization Line (80-200 tons/hour): Shredder+ Rotary Trommel Screen + Magnetic Separator + Air density separator + NIR Optical Separator + Eddy Current Separator + RDF Baler.

2. Construction Waste Sorting Line (100-300 tons/hour): Vibrating feeder + soil removal screen + crushing + multi-layer screening + multi-stage air separation + magnetic separation, producing aggregates, metals, and RDF.

3. Waste Plastic Specialized Sorting Line (3-10 tons/hour): Crushing + hot washing + friction cleaning + rinsing + dewatering + NIR color sorting/material sorting, producing high-purity plastic fragments.

4. Drive and Layout: Supports all-electric drive or diesel-electric hybrid power. Flexible layout: fixed, semi-mobile skid-mounted, or container modular design.

III. Technical Objectives (Guiding Principles)

• Processing Capacity: 50–400 tons/hour (expandable through module stacking).
• Sorting Purity: Target plastic/metal sorting purity ≥95%; stable RDF calorific value.
•  Resource Recovery Rate: Based on feed composition, the overall recovery rate of recyclables is increased by 30%-70%. – Energy and Water Consumption: Optimized system design reduces power consumption per ton of processing; provides a water circulation system to achieve near-zero wastewater discharge.
• System Availability: ≥92% (equipped with a preventative maintenance system and intelligent early warning).
• Environmentally Friendly: Negative pressure dust control in the workshop; noise level ≤85 dB(A).

IV. OEM/ODM Options

• Branding and Interaction: Equipment colors, brand labeling, multilingual control interface, customized technical documentation.
•  Modular Options: Combine crushing, screening, sorting (magnetic separation, eddy current, optical air separation, etc.), and cleaning modules according to requirements.
• Environmentally Friendly Packaging: Fully enclosed or semi-enclosed plant design, equipped with a high-efficiency dust and odor removal system.
•  Localization Compliance: Provides CE/ISO certification; electrical systems are compatible with target country standards.

V. Delivery Cycle and Deliverables

• Standard System: 45-60 days | Deeply Customized System: 60-90 days
• Deliverables: Process flow diagram (P&ID), plant layout diagram, foundation load diagram, electrical wiring diagram, list of vulnerable parts, CE/ISO certificate, complete set of export customs documents.
• On-site Service: Engineers will be dispatched to guide the installation and commissioning of equipment and provide comprehensive operation and maintenance training.

VI. Expected Benefits

• Reduced Operating Costs: Automation and efficient sorting reduce reliance on manual labor and improve unit processing efficiency.
• Maximized Output Value: Obtain high-market-purity recyclables (such as plastic sheets and scrap metal) and standardized RDF, increasing revenue.
• Project Adaptability: Modular design supports rapid relocation and expansion, flexibly adapting to changes in the project cycle and scale.
• Environmental Compliance: The system meets stringent environmental emission requirements, helping clients successfully pass environmental impact assessments.

VII. Application Scenarios

• Municipal Solid Waste: Emphasis is placed on efficient bag breaking and organic matter separation. The core lies in NIR sorting accuracy and RDF quality control.
•  Construction and Renovation Waste: Focuses on the separation of lightweight materials (plastics, wood) and aggregate cleanliness, requiring enhanced soil removal and air separation processes.
• Waste Plastic Bags: The core lies in deep cleaning and high-precision material/color sorting to achieve food-grade recycling requirements.
• Industrial Waste: Customized sorting and recycling processes are tailored to the characteristics of the materials (e.g., scrap car parts, waste wires).

IX. Q&A

Q: Can you handle mixed waste or waste requiring pre-sorting?

A: Our core strength lies in handling complex mixed waste (such as MSW). The system was designed from the outset with bag breaking, screening, and multi-stage sorting in mind, achieving efficient back-end sorting without requiring meticulous source separation by residents.

Q: What data is needed to obtain a solution?

A: Please provide as much as possible: 1) The approximate proportions of waste components (plastics, paper, metals, organic matter, etc.); 2) Hourly/Daily processing target; 3) Desired product types and standards (e.g., plastic purity, RDF calorific value); 4) Site limitations and environmental requirements.

Q: How automated is the system? Can it reduce manual labor?

A: The system is highly automated, with operations from feeding to packaging handled from the central control room. Key sorting stages utilize intelligent sorting equipment such as optical and eddy current systems, replacing a significant amount of manual sorting, typically reducing manual labor on the sorting line by over 70%.
