Plastic Automotive Parts ABS PS PP Household Appliance Waste Plastic Crushing Shredding Recycling Line

Project Overview

This heavy-duty shredding line is engineered for the high-volume size reduction of a wide range of rigid plastic waste, specifically targeting ABS, PS, and PP materials sourced from end-of-life household appliances, automotive parts, plastic toys, and large machine housings. Designed with versatility and robustness in mind, it efficiently processes bulky, irregularly shaped items that cannot be handled by standard crushers. The system ensures a continuous workflow with outputs ranging from 500 to 5000 kg/h, transforming challenging waste streams into uniform, clean-sized flakes ready for subsequent washing, separation stages in the recycling process.

Process Introduction

The process begins with a Chain Plate Conveyor that steadily feeds bulky whole items into the system. The material first enters a Dual-Shaft Shredder, where powerful, interlocking blades tear and shear the large plastic parts into smaller, manageable strips or chunks. An Over-Belt Magnetic Separator is then strategically positioned to automatically remove ferrous metalsfrom the material stream. The pre-shredded plastic proceeds into a Closed-Cell Crusher , where it is pulverized into the final, consistent flake size required for recycling. Finally, a Screw Conveyor transports the cleaned and sized plastic flakes efficiently to the next stage, such as a storage silo or a washing line, ensuring a fully automated and enclosed transfer to minimize dust and manual handling.

Technical Parameters

Key Features & Technological Advantages

1.Heavy-Duty Pre-Shredding for Bulky Items:The line is anchored by a robust dual-shaft shredder, specifically engineered to process large, voluminous, and irregularly shaped waste like appliance shells and automotive parts that standard crushers cannot accept, ensuring versatile feedstock compatibility.

2.Automated Metal Removal & Product Purity:An integrated over-band magnetic separator automatically detects and removes ferrous metal contaminants during the process. This critical step protects downstream size reduction equipment from damage and enhances the purity of the final flake product.

3.High-Efficiency Crushing into Uniform Sizing:Following pre-shredding, a high-torque closed-cell crusher precisely reduces the material into consistent, clean-sized flakes. This uniformity is essential for efficient subsequent processing in washing, extrusion, or pelletizing lines.
