Double Shaft Shredder for Plastic, Metal & Tire Recycling
This double shaft shredder uses low-speed, high-torque shear cutting to process plastics, metal drums, tires, bulky waste, and other difficult industrial materials. It is designed for stable throughput, lower downtime, and flexible blade configurations for different waste streams.
Why Choose a Shear Type Double Shaft Shredder
Low-speed dual-shaft shearing is widely used where heavy, irregular, or mixed materials need strong tearing force and stable continuous reduction.
Low-Speed High-Torque Shear Cutting
The dual shafts rotate at low speed with strong torque, allowing the machine to tear, shear, and reduce bulky or dense materials with stable output and lower dust than high-speed cutting systems.
Smooth Speed Reduction
Belt and reducer transmission helps absorb shock loading and protect the drive system during difficult shredding operations.
Custom Knife Thickness
Blade thickness options from 25 mm to 100 mm allow the machine to match different feedstock hardness and target output requirements.
PLC Control with Reverse and Overload Protection
PLC-based control helps manage reverse rotation, overload conditions, and general fault diagnosis. This improves uptime, reduces risk of jamming, and supports safer operation in demanding industrial environments.
Double Shaft Shearing vs. High-Speed Reduction
Different shredding principles serve different waste streams. Shear shredding is strongest where feedstock is bulky, mixed, or impact-heavy.
| Processing Factor | High-Speed Reduction | Double Shaft Shear Shredding |
|---|---|---|
| Bulky Waste Handling | Less ideal for heavy shock loading | Well suited to irregular and bulky materials |
| Torque at Low Speed | Lower low-speed tearing force | Strong tearing force under load |
| Dust and Impact | Higher impact and potential fines | Lower speed with controlled shear action |
| Mixed Material Tolerance | More feed prep may be required | Better for mixed industrial waste and drums |
How the Double Shaft Shredding Process Works
A heavy-duty shear reduction process built for continuous operation and mixed feedstock conditions.
Material Loading
Bulky plastics, drums, tires, wood, or mixed industrial waste are fed into the hopper.
Dual Shaft Shearing
The twin shafts pull material inward and cut it through opposing knife stacks with strong shear force.
Auto Reverse Protection
When overload or bridging occurs, the PLC commands reverse rotation to release material and restore flow.
Discharge for Next Stage
Reduced material exits for conveying, sorting, secondary crushing, or full recycling line integration.
Ideal Applications
This machine is designed for users who need one shredder to handle multiple heavy-duty waste categories.
Plastic and Metal Drums
Reduces large containers into manageable pieces for downstream sorting and recycling.
Tires and Automotive Parts
Handles tires, bumpers, rubber parts, and road barriers that require strong tearing action.
Wood and Bulky Waste
Processes mixed wood scrap and bulky industrial waste with continuous heavy-duty performance.
General Industrial Waste
Useful for mixed production scrap streams where a single material-specific shredder is not enough.

Frequently Asked Questions
Common questions about blade configuration, maintenance, and long-term operation.
Yes. Blade thickness from 25 mm to 100 mm can be selected according to material hardness, shredding force requirements, and desired output size.
Routine maintenance includes blade inspection or sharpening, bearing and gearbox lubrication, belt tension checks, and regular cleaning of the shredding chamber.
The machine can include emergency stops, guards, overload protection, reverse rotation to clear jams, and PLC diagnostics for safer operation.
With proper maintenance and correct knife selection, the machine structure is designed for long-term industrial service, typically around 10 to 15 years.
