Single-Shaft Shredder

Main Structure

A single-shaft shredder is a robust size-reduction machine designed for processing various materials, particularly plastics, in recycling applications.

Key structural components include:

Hopper – can be from the top or from the side.

Rotor – A heavy-duty rotating shaft equipped with hardened steel blades that cut and tear the material.

Blades/Cutters – Typically made from high-strength alloy steel (e.g., D2/SKD11), which are mounted on the rotor and perform the shredding action.

Screen/Grate – A perforated mesh that controls the output particle size; smaller holes produce finer shreds.

Electric Drive System – together with gearbox to power the rotor.

Pushing System – A hydraulic swing-arm or horizontal pusher plate forces material toward the rotor for consistent feeding.

Frame – Heavy-duty steel construction to withstand high torque and impact forces.

Control Panel – Allows operators to adjust and monitor performance, and ensure safety.

Application in Plastic Recycling

Single-shaft shredders are widely used in plastic recycling for:

Size Reduction – Breaking down large plastic items (e.g., lumps, cut-offs, pipes, films) into smaller flakes for further processing.

Pre-Shredding – Preparing mixed or bulky plastics before granulation or extrusion.

Waste Volume Reduction – Minimizing storage and transportation costs by compacting plastic waste.

Post-Consumer & Industrial Waste – Handling rigid plastics (e.g., HDPE, PP, ABS, PS) and flexible materials (e.g., LDPE LLDPE films, PP big bags).

Key Features

High Torque & Low Speed – Designed for tough materials, operating at 20-72 RPM to ensure efficient shredding without overheating.

Versatility – Can process a wide range of plastics, including thick-walled and reinforced materials.

Durability – Hardened blades and robust construction ensure long service life even under heavy use.

Customizable Output Size – Adjustable screen/grate allows control over shredded particle dimensions.

Low Maintenance – Easy access to blades for replacement.

Safety Mechanisms – Overload protection, emergency stop, and automatic reversal to prevent jamming.

Suitable Plastic Types

Single-shaft shredders can handle various plastics, including:

Rigid Plastics: HDPE, PP, PVC, ABS, PS, PET (e.g., bottles, crates, automotive parts).

Flexible Plastics: LDPE, LLDPE films, PP big bags, and woven sacks.

Engineering Plastics: Nylon, PC, POM (if equipped with appropriate blades).

Composite Materials: Plastic-metal hybrids (e.g., electronics housings) when designed for such applications.

SS series of single-shaft shredder: horizontal pusher.
