Made of SKD-11 alloy steel, hardened to HRC58-62°, it is wear-resistant and chip-resistant. Compatible with various single-shaft shredders, it is specifically designed for crushing PE/PP pipes, plastic buckets, and sprue, producing clean, non-stick cuts. Custom sizes are available, making it a cost-effective accessory for small and medium-sized plastic recycling plants.
High-quality shredder blades, through process optimization and design upgrades, possess core advantages suitable for industrial production:
First, it features high precision. The blades produced by regular manufacturers undergo quenching treatment and multiple precision grinding processes, with dimensional tolerances controlled within ±0.002mm. After being put on the machine, the equipment operates smoothly, and there are no obvious burrs or cracks when shredding materials.
Second, it can be reused and customized. Types like single-axis square knives can be repeatedly ground. At the same time, it supports customization of size, number of teeth and hardness according to the model of the shredder and the characteristics of the material. It can also provide OEM/ODM services.
Thirdly, it has a wide range of adaptability. Through the differentiated design of tooth shape and knife shape, it can not only handle solid block materials but also flexible fiber materials, meeting the shredding needs of multiple industries.
| Single-shaft shredder blades | They are mostly square moving blades, with curved edges on all four sides and a tapping hole in the middle. The part from the blade edge to the middle hole is concave inward. During operation, they need to be used in conjunction with the fixed blades on the blade frame. This type of blade is suitable for single-shaft equipment operating at medium speed. After shredding, the particles are small and uniform, and the maintenance and replacement operations are relatively simple. |
| Double-shaft shredder blades | Commonly, they are designed as claw blades, available in various specifications such as 3 claws, 8 claws, and 12 claws. The blades are installed on the double shafts in an interlaced manner. Relying on the low-speed and high-torque operation of the dual shafts, materials are shredded through the shearing and squeezing action between the blades. The wear is uniform and it is suitable for processing large and hard-to-tear materials. |
| Four-shaft shredder blades | Also mainly composed of claw blades, the structure of the four-blade roller enables it to form multi-directional shearing surfaces during shredding. It is particularly suitable for complex materials such as electronic waste and contaminated soft materials. The crushed particles are medium-sized and uniform, and have a good anti-entanglement effect. |
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.
