Rigid Plastics Shredder Machine
Engineered for tough rigid plastics (HDPE/PP/ABS/PC): crates, pallets, pipes, housings, injection sprues, and extruder purgings/lumps—delivering stable size reduction and efficient volume reduction for downstream recycling.
Why Choose Our Rigid Plastics Shredder?
Built for bulky, thick, and high-strength rigid plastics—focused on stable throughput, safety, and serviceability.
Continuous Feeding, Fewer Jams
Designed for bulky and irregular rigid plastic parts. A stable feeding structure helps maintain throughput and reduce unplanned stoppages caused by bridging or clogging.
Aggressive Cutting for Thick-Wall Rigid Plastics
A heavy-duty rotor paired with wear-resistant knives handles thick pipes, pallets, rigid sheet/parts, and dense lumps with reliable cutting performance.
Service-Friendly, Lower Operating Cost
Maintenance-oriented design supports routine servicing and parts replacement. Knife and wear-part configurations can be optimized for your material to extend service life.
Smart Controls, Safe Operation
PLC control supports start/stop, forward/reverse, and automatic overload protection to improve safety and stability in long-running recycling operations.
Materials & Applications
Rigid plastics are strong and dimensionally stable, widely used in household and industrial products. Shredding is a key first step to reduce size and improve downstream washing and pelletizing efficiency.
Typical Products
- Bins, totes, crates, and housings (appliances, electronics, industrial casings)
- Plastic pallets, rigid sheets, thick thermoformed parts, and off-cuts
- HDPE/PVC/PP pipes and thick-wall fittings
- Injection sprues/runners and extruder purgings/lumps
Common Polymers
Working Principle & Key Components
Optimized for rigid plastics—from feeding and cutting to safe discharge.
How Does a Rigid Plastics Shredder Work?
Material enters the hopper and is guided toward the rotating rotor. The rotor knives shear the plastic against a fixed counter-knife for stable size reduction. Once the pieces meet the target size, they discharge and proceed to downstream recycling steps.
- Hopper / feeding structure: Improves feeding for bulky rigid parts and reduces bridging risk.
- Rotor & knives: Wear-resistant design for long service life on rigid plastics.
- Coupling transmission: Reduces vibration and protects the main shaft and gearbox.
- PLC control system: Start/stop, forward/reverse, and overload protection for safer operation.

Proof: Build Quality, Safety & Serviceability
For industrial purchasing, details matter. Below are the checkpoints and options we can provide to support a reliable rigid plastics shredder machine selection.
Manufacturing & QC Evidence
Process controls and inspection checkpoints that reduce risk.
- Bearing / gearbox options: Brand options available on request (per project and supply chain).
- Heat treatment: Knife and wear-part heat treatment process matched to your material (rigid plastics / light contamination).
- Rotor dynamic balancing: Helps minimize vibration, noise, and bearing wear.
- Assembly tolerances: Critical-fit checks for shaft, coupling, and bearing seats.
- Pre-shipment testing (FAT): No-load + functional run, current draw, temperature rise, and control logic verification; test video available.
Safety & Protection
Designed to protect people and equipment in real-world recycling.
- Overload logic: PLC monitors load and triggers protection to avoid motor/drive damage.
- Reverse strategy: Auto reverse / recovery logic for bridging or stalled cutting (parameterized).
- E-stop & interlocks: Emergency stop + safety interlock readiness (e.g., access door/cover protection, depending on configuration).
- Metal contamination response: Support for upstream magnet separation; optional metal detection solutions can be discussed for high-risk streams.
Maintenance & Serviceability Details
Practical design choices that keep downtime low.
- Knife change method: Service-access design for faster knife rotation/replacement (final method depends on model).
- Knife steel options: D2 / SKD-11 options available based on wear expectation and budget.
- Screen change: Screen configuration and replacement method available for controlled output size.
- Lubrication points: Clear lubrication points and maintenance checklist support for routine servicing.
