Heavy Duty Single-Shaft Shredder Machine
Powerful size reduction for hard plastics: Turn solid lumps, pipes, and pallets into uniform particles.
Why Choose Our Single-Shaft Shredder?
Engineered for efficiency, low maintenance, and precise material control.
Uniform Particle Size
Equipped with a screen sieve to ensure consistent output size, unlike double-shaft shredders which produce random strips.
Smart Hydraulic Ram
An automated hydraulic pusher forces material against the rotor, maximizing throughput without jamming.
Lower Maintenance
Fewer blades and a simpler drive mechanism mean reduced spare parts cost and easier blade replacement.
High Efficiency
Optimized rotor geometry and high-speed operation ensure rapid processing of wide range of materials.
Key Components & Working Principle
Robust engineering designed to handle tough materials.
How It Works
Material falls into the hopper and is pushed by a hydraulic ram against a spinning rotor. The rotor is fitted with cutting blades that shear the plastic against a fixed counter-knife. Once the material is small enough, it passes through a screen at the bottom. Pieces that are too large are swept back up for re-shredding.
- Rotor & Blades: High-wear resistant alloy steel for long sharpness.
- Hydraulic Pusher: Smart load-sensing to prevent overloading.
- Screen: Interchangeable mesh sizes (20mm-100mm) to control output.
Single-Shaft vs. Double-Shaft
Which shredder is right for your application?
While both machines reduce material size, they serve different purposes:
Single-Shaft Shredder
Best for: Solid, thick, or hard materials (Purging lumps, runners, pellets, thick pipes, wood, paper rolls).
Pros: Controlled output size (screen), high processing speed for specific materials.
Double-Shaft Shredder
Best for: Hollow, voluminous, or lightweight materials (Films, drums, tires, electronics).
Pros: High torque for shearing, no hydraulic pusher needed, but random output size.
