Plastic shredders, often referred to as plastic granulators, are essential machines in the recycling and waste management industries. Designed to tear and crush materials into smaller particles or flakes, these machines handle larger, harder plastic waste that standard crushers cannot process—such as car bumpers, pipes, drums, and plastic buckets. At Rumtoo Machine, we engineer robust, efficient shredding solutions tailored to diverse industrial needs, ensuring optimal performance, durability, and value.

All You Need to Know About Plastic Shredders
Plastic shredders are specialized machines designed for reducing hard and bulky materials, crucial in plastic recycling lines. They are primarily categorized into single-shaft and twin-shaft shredders, based on the number of cutting rotors.
Rumtoo Machine provides comprehensive guidance on shredder applications, mechanisms, selection criteria, and operational best practices, helping you choose between single-shaft and twin-shaft models based on your specific needs.
What Are Plastic Shredders Used For?
Equipped with alloy blades resistant to high temperatures and wear, our shredders efficiently process pipes, films, plastic bottles, and other plastic products. They can also be customized to handle metals, wood, and more. Common applications include:
- Pipe Profiles
- Plastic Bottles
- Glass Products
- PP/PE Film
- Nylon
- PET
- PVC/HDPE
- Metal
- Woods
- Car Shell
Plastic Shredder Parts
Hopper
The hopper feeds material into the shredder. Its size determines the maximum input material dimensions. Options include fixed hoppers for smaller, softer materials and mobile hoppers for larger items.
Shredding Chamber
This chamber houses rotating blades, fixed blades, screens, and other components where actual shredding occurs.
Blades & Knives
Rumtoo Machine recommends specific blade types—such as block knives, counter knives, shredder blades for single-shaft units, or rotor shears for twin-shaft models—based on your material.
Discharge Screen
Screens define output particle size. We offer various designs: round hole, honeycomb, kidney, and serrated/zig-zag, depending on desired material fineness.
How Do Plastic Shredders Work?
When powered, the motor rotates dynamic blades against fixed blades in the cutting chamber. Material entering the chamber is cut and ground through the interaction between these components, facilitated by gravity and mechanical force.
Why Choose a Plastic Shredder?
- Flexibility: Customizable with different rotors, screens, and blade structures.
- Ease of Cleaning: Simple cover opening for maintenance and cleaning (power off for safety).
- Powerful Performance: Lower operational speed but high torque for tearing hard metals and materials.
- Wide Application: Processes plastics, wood, metals, glass, cardboard, and more.
Considerations When Buying a Shredder
#1 Material Type
Physical properties greatly influence shredder and blade selection. Inform our team about your material for accurate recommendations.
#2 Material Size
We customize hopper size and shaft length based on input material dimensions, optimizing efficiency and cost.
#3 Single or Twin Shaft?
- Single-shaft: Best for mixed, varied materials.
- Twin-shaft: Ideal for hard metals, barrels, and tough items.
#4 Mobile or Fixed Hopper?
- Mobile hopper: Suitable for large, bulky materials.
- Fixed hopper: Designed for smaller, softer items.
#5 Blade Materials
Blade material depends on shredding needs. We recommend Cr12MoV, D2, DC53, or SKD-11 based on application.
#6 Overall Production Line
Consider full system requirements, including discharge port location and production goals, for seamless integration.
Types of Shredders by Blade
Rotor Shears
Used in twin-shaft shredders for metals and hard materials. Material is fed into the chamber, caught between counter-rotating shears, and torn apart as gaps narrow.
Shredder Blades/Knives
Rectangular, curved blades mounted on single shafts, ideal for mixed materials. Perfect for versatile shredding tasks.
Types of Shredders by Shaft
Single-Shaft Shredder
Versatile for various materials. Features a rotor with a hydraulic ram for pushing waste into the cutting zone.
Twin-Shaft Shredder
Excellent for hard metals and materials. Operates at lower speeds with high torque, using opposing blades to crush items effectively.
Types of Shredders by Blade Material
Selecting the right steel ensures durability and performance:
- 9CrSi: Alloy tool steel, high hardness, wear-resistant but brittle. Ideal for soft materials like rubber, fiber, paper.
- SKD-11: Cold work tool steel, high wear and impact resistance. Suitable for wood, furniture, hard plastics.
- Other Alloys: Options like Cr12MoV, D2, and DC53 offer versatility for specific needs.
