Industrial Shredder and Pulverizer Blades – High-Strength Cutting Solutions for Material Reduction and Recycling

Shredder blades and pulverizer blades are essential components used in the material reduction process across a broad range of industries, including plastic recycling, metal recovery, waste processing, and industrial manufacturing. These blades are engineered to perform heavy-duty cutting, tearing, and pulverizing actions on various materials—ranging from soft films and rubber to hard plastics, fibers, and metals.

Our shredder and pulverizer blades are manufactured using premium-grade tool steels and alloy steels, including materials such as 9CrSi, SKD-11, D2, H13, and tungsten carbide composites for extreme wear resistance. Through precision heat treatment, these blades reach hardness ratings from HRC 55 to HRC 63, ensuring a long working life under continuous industrial operation.


Key Features

  • High-Quality Materials
    We select raw materials based on the application’s intensity and abrasiveness. Whether your operation requires impact resistance or edge retention under high-speed cutting, we offer steel grades that meet those demands.

  • Excellent Wear Resistance
    With advanced heat treatment processes such as vacuum quenching and cryogenic tempering, our blades resist wear, chipping, and deformation under pressure.

  • Customizable Designs
    We support custom manufacturing based on drawings or samples. Blade thickness, hole positioning, tooth profile, edge angle, and surface coatings (e.g., anti-corrosion or TiN) can all be customized to fit different pulverizer and shredder machines.

  • Precision Engineering
    All blades are CNC-machined and surface-ground for flatness, dimensional accuracy, and sharpness. Tighter tolerances result in cleaner cuts and lower energy consumption.


Blade Types and Applications

1. Shredder Blades (Single and Twin Shaft)

Shredder blades are widely used in waste reduction equipment such as single-shaft and double-shaft shredders. These blades typically have serrated or hook-shaped profiles and are made to tear and shear through solid and bulky waste.

Applications include:

  • Plastic drums, containers, and pipes

  • Scrap metal and aluminum sheets

  • Tires and rubber

  • Municipal solid waste

  • Electronic waste (WEEE)

2. Pulverizer Blades / Disc Blades

Pulverizer blades, also referred to as pulverizing discs, are commonly used in plastic pulverizers that grind materials into fine powder or granules. These machines are often employed for processing virgin plastic flakes, recycled PET, HDPE, or PVC materials into uniform particles for re-molding or compounding.

Typical blade sizes:

  • Tooth-type disc blades for rigid plastics

  • Segment disc blades for soft or elastic materials

  • Flat disc blades for high-speed pulverizing

Applications include:

  • Pulverizing thermoplastics (PE, PP, ABS, PA, PC)

  • Masterbatch preparation

  • Powder coatings

  • Waste plastic film recycling

3. Granulator and Crusher Blades (Pulverizer Pre-Stage)

Before pulverization, materials often pass through granulators or crushers for size reduction. These blades feature straight or claw-shaped cutting edges for chopping bulk items into manageable fragments.

Used in:

  • Plastic injection and blow molding waste

  • Film and bag recycling

  • PET bottle flakes production
