OEM Shredder Rotor Blades

 

 

 

At SHJ KNIFE, we manufacture OEM and custom shredder rotor blades for industrial shredding, recycling and material size reduction machines. Our rotor blades and rotor knives are made according to customer drawings, samples, dimensions, material requirements and working conditions.

This page focuses on customized industrial rotor blades, not standard catalogue parts only. If you need blades with specific hole patterns, thickness, mounting structure, edge design or material hardness, our team can help check the details before production and quotation.

 

 

 

Customers usually contact us when their existing rotor blades are worn, broken, difficult to source, or when standard blades cannot match the machine structure. In many cases, customers only have worn blade samples, photos, dimensions or machine information. SHJ KNIFE supports custom production based on these technical details.

 

• Custom rotor blades by drawing, sample or dimensions
• OEM industrial blade manufacturing for shredding machines
• Material, hardness and edge design matched to working conditions
• Stable finishing and protective packaging for repeat supply

 

 

In industrial shredding machines, rotor blades are rotating knives mounted on the rotor or shaft. Stator blades, also called fixed blades, bed knives or counter knives, stay in a fixed position and work together with rotor blades during cutting.

If you need rotor-blades only, not stator-blades, please send the blade drawing, sample photo, dimensions, hole pattern and application details. Our team can help confirm the blade type before quotation.

 

 

Blade Type	Position	Common Names
Rotor Blades	Mounted on rotor or shaft	Rotor knives, rotating blades, cutter blocks
Stator Blades	Fixed position	Fixed blades, bed knives, counter knives
Blade Sets	Rotor blades + fixed blades	Shredder blade sets, cutting knife sets

 

These are industrial cutting knives for shredding and recycling machines, not fan blades or turbine blades.

 

 

SHJ KNIFE manufactures shredder rotor blades according to the technical information provided by customers. Clear blade information helps reduce communication time and improve quotation accuracy.

 

 

Customer Provides	SHJ KNIFE Supports
Blade drawing	Production according to drawing
Worn blade sample	Reverse check dimensions and structure
Blade dimensions	Confirm length, width, thickness and hole pattern
Hole position	Match mounting structure and assembly requirements
Material requirement	Select suitable tool steel or alloy steel
Hardness requirement	Adjust heat treatment for working conditions
Working material	Recommend edge design and material choice
Order quantity	Support sample order and repeat production

 

 

Our custom shredder rotor blades are used in industrial material size reduction applications. The blade material, hardness, edge angle and surface finish can be adjusted according to the material being shredded and the working conditions of the machine.

 

Application	Typical Materials	Blade Focus
Plastic recycling and shredding	Film, bottles, lumps, mixed plastics	Wear resistance and stable cutting
Rubber and tire shredding	Rubber, tire pieces, mixed materials	Impact resistance and toughness
Waste material size reduction	Industrial waste and recycling materials	Material matching and blade strength
Pre-shredding before granulating	Plastic waste before granulating or crushing	Reliable fit and repeat production

 

 

 

 

For customized industrial blades, inspection is a key part of production. SHJ KNIFE checks blade dimensions, hole position, surface finish, edge condition and hardness according to customer requirements and application needs.

Before packaging, blades are reviewed for fit-related details such as length, width, thickness, mounting holes and edge condition. This helps reduce installation problems and supports stable repeat orders.

 

 

 

Shredder rotor blades are heavy, sharp and easy to damage during long-distance transportation if they are not packed properly. SHJ KNIFE uses protective packaging according to blade size, weight and order requirements.

Packaging options may include anti-rust oil protection, edge protection, separate blade wrapping, carton or wooden case packaging, clear labeling for repeat orders and additional protection for heavy or sharp blades.

 

 

 

SHJ KNIFE provides OEM and customized manufacturing for industrial blades used in shredding, recycling and material size reduction machines. We do not rely only on standard blade models. Our team works from customer drawings, samples, dimensions and technical requirements to provide suitable blade manufacturing solutions.

 

• OEM production according to customer requirements
• Customized blade dimensions and structures
• Material and hardness matching
• Heat treatment and edge processing
• Surface finishing and protective packaging
• Repeat production for long-term supply

 

 

Some customers provide machine brand, model or blade photos to help identify blade dimensions and structure. This information is used only for technical reference and compatibility checking.

SHJ KNIFE is an independent industrial blade manufacturer. We do not claim to be an original equipment manufacturer, authorized distributor or official supplier of any third-party machine brand.

1. What are shredder rotor blades?

Shredder rotor blades are rotating cutting knives mounted on the rotor or shaft of a shredding machine. They work with fixed blades or bed knives to cut and reduce materials such as plastic, rubber and waste materials.

 

2. Can you make rotor-blades, not stator-blades?

Yes. If you need rotor-blades only, please send your drawing, sample photo, dimensions, hole pattern and application details. We can help confirm the blade type before quotation.

 

3. Can you manufacture rotor blades without a part number?

Yes. Many customized industrial blades are made from drawings, worn samples, photos, dimensions or machine information. A clear drawing or sample helps improve accuracy.

 

4. What materials can be used for shredder rotor blades?

Material selection depends on the working material and machine conditions. Common choices include tool steel and alloy steel with suitable heat treatment. SHJ KNIFE can recommend material options based on your application.

 

5. Do you supply original machine brand blades?

SHJ KNIFE is an independent industrial blade manufacturer. We provide OEM and customized industrial blades according to customer requirements. We do not claim to supply original, genuine or authorized blades of any third-party machine brand.

 

6. What information is needed for quotation?

Please send blade drawings, dimensions, hole positions, material requirements, hardness requirements, quantity and working material. Sample photos are also helpful if drawings are not available.
