Heavy-Duty Shredder Blades & Grinder Teeth

Heavy-Duty Shredder Blades & Grinder Teeth

Persistools heavy-duty shredder blades and grinder teeth are designed for demanding recycling and size-reduction applications where cutting tools are exposed to repeated impact, abrasive materials, contamination, and continuous mechanical load.

Unlike precision cutting blades, shredder teeth must withstand a combination of impact, compression, abrasion, and irregular material contact.

For this reason, material selection and tooth construction are especially important.

Different designs can be manufactured according to the processed material, rotor configuration, machine power, feed size, and expected wear conditions.

Typical applications include:

• Plastic recycling
• Rubber and tire processing
• Wood and biomass shredding
• Industrial waste recycling
• Cable and wire recycling
• Metal-containing waste processing
• Electronic waste processing
• General size-reduction equipment

Different Materials for Different Working Conditions

Persistools shredder blades and grinder teeth can be supplied in several material and construction options.

Tool Steel / HSS

Tool steel and high-speed steel designs provide good toughness and impact resistance, making them suitable for applications where the cutter is subjected to repeated shock loads or unpredictable material contact.

TCT-Tipped Shredder Teeth

TCT-tipped designs use brazed tungsten carbide inserts at critical cutting and wear areas.

This construction combines the toughness of a steel body with the high wear resistance of tungsten carbide, providing a practical solution for abrasive recycling materials and long production cycles.

Solid Carbide Teeth

Solid tungsten carbide teeth provide extremely high wear resistance and dimensional stability.

Because carbide is less tolerant of heavy impact than steel, solid carbide designs are generally used in selected applications where abrasive wear is the primary concern and machine conditions are relatively controlled.

Built for Harsh Recycling Environments

Recycling equipment rarely processes perfectly clean and consistent material.

Shredder teeth may encounter:

• Sand and mineral contamination
• Metal fragments
• Glass particles
• Reinforced plastics
• Fibers and fillers
• Hard inclusions
• Irregular feed sizes
• Repeated impact loading

A suitable shredder tooth therefore requires more than high hardness alone.

The balance between toughness, wear resistance, cutting geometry, and structural strength directly affects tool life and machine stability.

Persistools can adjust material grade, heat treatment, carbide grade, brazing structure, tooth geometry, and cutting-edge design according to the actual working conditions.

Custom Replacement Shredder Teeth

Most industrial shredder blades and grinder teeth are machine-specific components.

Persistools can manufacture replacement cutters according to:

• Customer drawings
• Original samples
• Machine model
• Rotor dimensions
• Mounting holes and interfaces
• Cutting-edge geometry
• Processed material
• Required hardness
• Impact conditions
• Wear conditions

Different steel grades, carbide inserts, and complete solid carbide designs can be selected according to the required balance between durability and impact resistance.
