Anvils

The cutting board of the crusher is a key wear-resistant component in industrial metal and paper crushers. As a fixed blade, it works together with the rotating hammer to cut and tear materials.

  • Function: Cooperate with the hammer to cut materials, improve crushing quality, and reduce motor load.
  • Material: High manganese steel or low-alloy steel containing chromium, nickel, and molybdenum are commonly used, with high wear resistance and impact resistance.
  • Structure: It is often made into a segmented structure of three or four pieces, which is easy to install and replace; Some designs can adjust the gap with the rotor through a top screw.
  • Application: Used for car crushers, scrap metal processing machines, plastic and paper crushing equipment, etc.

Breakers 

Heavy-duty components used to break down large, dense materials in shredding systems. Essential for waste management, metal recycling, and plastics processing—improve crushing efficiency, increase throughput, and protect equipment.

  • Breaker Bars: Used in horizontal and vertical shredders; high impact resistance for materials like auto parts and industrial waste.

  • Bale Breakers (Debalers): Break compressed bales (e.g., PET bottles) in plastics recycling to prevent overloads.

  • Pre-Breakers: Perform initial size reduction before fine grinding; ensure uniform particle size.

  • Wear Parts (Teeth / Hammers): Manganese steel hammers and teeth that work with breakers to tear and crush materials.

Cutter Bars

Critical wear parts that shear materials in industrial, agricultural, and recycling shredders. Made from hardened steel or tungsten carbide for durability and high impact resistance. Provide clean shearing, reduce bowing, and improve product quality.

  • Industrial / Recycling Cutter Bars: Include breaker bars, anvils, and counter blades. Commonly made from manganese steel or chromium carbide. Used in scrap processing.

  • Agricultural / Flail Cutter Bars: Hard-surfaced blades for cutting vegetation; designed for specific rotor configurations.

  • Mower Cutter Bars: Used in mowing equipment; feature single‑ or double‑action mechanisms.

Liners

Durable, custom-fit plastic bags that simplify paper disposal, prevent mess, and protect shredder bins. Used for home, office, and high‑security shredders. Capacities range from 4 to 56 gallons. Common brands: Fellowes, Destroyit, SEM, Swingline.

  • Capacity & Size: Match to bin volume—7–10 gallons for small/medium units, 30–50+ gallons for commercial models.

  • Fit: Choose bags designed for your brand or bin shape (round vs. rectangular) for a secure fit.

  • Material Strength: Medium‑to‑heavy duty plastic resists tearing, especially with cross‑cut or micro‑cut waste.

  • Compatibility: Some brands offer specialized high‑security bags (SEM, Destroyit) or bags for specific models (Swingline Stack‑and‑Shred).
