Crusher blades are high-hardness, high-wear-resistant cutting tools installed on the core rotor of a crusher. Their function is to use the impact, shearing, tearing and other forces generated by high-speed rotation to crush various solid materials into smaller particles or powders.
Product Specification Table of Crusher Blades
| Project | Detailed description | Notes and explanations |
| Product model | Example: PJ-SKD11-200, PJ-MN13-300 | Name according to the "type - material - size" rule |
| Material | Optional: SKD-11 alloy steel/Cr12MoV alloy/high manganese steel (Mn13)/hard alloy insert / 304 stainless steel | Different materials correspond to different applicable materials |
| Hardness (HRC) | Example: 58-62° (SKD-11), 50-55° (high manganese steel) | It is tested by a Rockwell hardness tester before leaving the factory |
Dimensional parameters | Length × width × thickness: For example, 200mm×80mm×15mm Cutting edge Angle: Example 30°/45° Compatible shaft diameter: For example, Φ50mm | Supports customization of non-standard sizes |
| Process treatment | Optional: High-temperature quenching/tempering/precision water grinding/laser cladding/titanium anti-sticking coating | The process determines the wear resistance and anti-chipping performance of the blade |
| Compatible device type | Optional: Jaw crusher/impact crusher/Twin-shaft shredder/Hammer crusher/Plastic crusher | The equipment model and production capacity need to be matched |
| Applicable materials | Example: Plastic sprue material/ore/scrap metal/wood/construction waste/tire rubber/electronic waste | Select the corresponding material blade according to the hardness of the material |
| Service life | Example: ≥3000 hours (plastic crushing), ≥5000 hours (ore crushing) | It is related to the hardness of the material and the frequency of use |
| Installation method | Optional: Bolt fixation/welding fixation/snap-on quick installation | Mark the dimensions of the installation holes: for example, Φ12mm×4 holes |
| Enforce standards | National standard GB/T 14404-2021, industry standard JB/T 10256-2018 | Customization is available upon providing drawings or samples |
| Customized service | Support processing based on provided drawings/OEM/ODM/ size customization/material customization | Export products can be marked with international standards |
Why Choose Us
Deep technical expertise and professional customization capabilities: Our team is well-versed in the crushing characteristics of various materials such as plastic, metal, wood, rubber, etc. We will not merely sell you standard products. Instead, we will carefully inquire about your specific materials, working conditions and pain points (such as insufficient production capacity, rapid wear, easy material jamming, etc.), and recommend or even tailor the most suitable blade design, material and edge treatment solution for you.
Outstanding materials and heat treatment processes: The core lies in the inner quality. We insist on using high-quality alloy tool steels that meet national standards or are well-known brands (such as 9CrSi, Cr12MoV, D2, etc.). "Heat treatment is our soul." Equipped with advanced heat treatment equipment (such as vacuum quenching furnaces) and strict process curve control, it ensures that each blade reaches the golden balance point of hardness and toughness. This means: the wear resistance is enhanced by more than 30%, the impact fracture resistance is stronger, and ultimately it brings you a longer service life and lower ton consumption cost.
Precision manufacturing and strict quality control: Precision determines performance. We use CNC numerical control machining centers for precision processing to ensure that the blade size, hole position and cutting edge Angle are exactly the same.
Focus on niche fields and solve your specific problems:
Facing glass fiber, circuit boards, and recycled materials containing sand and impurities? We offer hard alloy (tungsten carbide) inserts with a wear-resistant service life 5 to 8 times that of ordinary inserts.
Are large bundles of film and fibers prone to entanglement? Our special claw knife design can effectively grasp materials and prevent entanglement.
Facing high-hardness metals? Our high-strength modular shredder knife shaft offers unparalleled impact resistance.
Need food-grade certification? We offer stainless steel materials that meet standards and polishing processes.
