Double Shaft Shredder Application Case for Plastic Waste Processing in Spain
Published On: July 29, 2026
Project Overview
LANGBO Machinery recently supplied a Double Shaft Shredder Machine solution for a plastic recycling company in Spain.
The project was developed to support the customer's processing of different types of plastic waste generated from industrial production and recycling operations.
The processed materials include:
- Plastic production scraps
- Large plastic blocks
- PP and PE waste materials
- Mixed plastic recycling materials
The customer required a size reduction solution that could handle irregular plastic waste before further recycling processes.
LANGBO Machinery provided a customized Double Shaft Shredder to improve the customer's plastic waste preparation workflow.
Customer Background
The Spanish customer specializes in plastic recycling and material recovery services.
The company collects and processes plastic waste from:
- Plastic manufacturing plants
- Packaging industries
- Industrial production facilities
Before upgrading the equipment, the customer mainly relied on conventional processing methods for large plastic waste materials.
As the volume and variety of incoming plastic waste increased, the customer required a shredding system that could handle different material shapes and sizes.
Project Requirements
Processing Bulky Plastic Waste
Plastic recycling facilities often receive materials with different characteristics, including:
- Large plastic pieces
- Irregular shaped waste
- Production leftovers
- Mixed plastic materials
The customer needed equipment capable of reducing the size of these materials before further recycling steps.

Improving Recycling Preparation Process
The customer's recycling workflow required:
Plastic Waste Feeding
↓
Double Shaft Shredding
↓
Material Size Reduction
↓
Further Recycling Processing
The main requirements included:
- Continuous material processing
- Suitable shredding structure
- Adaptability to different plastic waste types
Processing Challenge
Different Plastic Waste Characteristics
Plastic waste from different sources may vary in:
- Material thickness
- Shape and size
- Density
- Processing conditions
Therefore, selecting a suitable shredding solution was important for maintaining a stable recycling workflow.
Preparing Materials for Downstream Equipment
Before entering processes such as:
- Crushing
- Washing
- Granulation
large plastic waste usually needs initial size reduction.
The Double Shaft Shredder works as a primary processing machine to prepare materials for the next recycling stages.
LANGBO Machinery Solution
Based on the customer's requirements, LANGBO Machinery supplied a Double Shaft Shredder Machine designed for plastic waste processing applications.
The equipment includes:
- Double shaft cutting system
- Shredding chamber
- Drive system
- Control system
- Safety protection structure
The machine was integrated into the customer's recycling process to handle bulky plastic waste before further processing.
Main Equipment Configuration
1. Double Shaft Cutting System
The machine uses two counter-rotating shafts to process plastic waste.
The cutting movement helps:
- Pull materials into the cutting area
- Reduce large waste size
- Improve material preparation efficiency
2. Blade System
The cutting blades are configured according to the customer's material requirements.
The blade structure affects:
- Material cutting process
- Output particle size
- Long-term operation conditions
3. Drive and Control System
The control system manages machine operation.
Main functions include:
- Start and stop control
- Operating monitoring
- Safety protection
Application Areas
The Double Shaft Shredder supplied for the Spanish project is used for processing:
Plastic Manufacturing Waste
Including:
- Extrusion scraps
- Injection molding leftovers
- Production offcuts
Plastic Recycling Materials
Including:
- PP waste
- PE waste
- Mixed plastic materials
Industrial Waste Processing
Suitable for:
- Large plastic components
- Bulky plastic waste
- Recycling preparation processes
Project Results
After installation and commissioning with LANGBO Machinery technical support, the customer successfully integrated the Double Shaft Shredder into its plastic recycling workflow.
The project helped the customer achieve:
Improved Waste Preparation Process
Large plastic waste materials could be processed before entering downstream recycling equipment.
Expanded Material Processing Capability
The customer increased its ability to handle different types of plastic waste.
Better Recycling Workflow Integration
The shredder was connected with the existing recycling process, supporting continuous material preparation.
Reduced Manual Pre-Processing Steps
The automatic shredding process simplified the handling of bulky plastic materials.
Engineering Value
For plastic recycling companies, shredding is an important first step in waste preparation.
A suitable Double Shaft Shredder Machine helps manufacturers and recyclers process:
- Large plastic waste
- Industrial scraps
- Mixed plastic materials
before further recycling operations.
The correct shredder selection depends on:
- Material characteristics
- Waste size
- Recycling process requirements
- Downstream equipment configuration
Conclusion
The Double Shaft Shredder Application Case in Spain demonstrates how industrial shredding equipment supports modern plastic recycling processes.
By combining a double shaft cutting structure, material handling capability, and integrated control system, LANGBO Machinery provides customized shredding solutions for plastic waste processing applications.
This project shows the importance of selecting suitable size reduction equipment for improving plastic recycling workflows and preparing materials for further processing.
