Double-shaft Shredders For Tires, Plastic, Wood - China

Double-Shaft Shredders are mainly used for plastics – mixed plastics, plastic barrels or containers, etc.

; electronic appliances – waste home appliances; tires – car tires, truck tires with thick steel wires removed, etc.

; wood – wooden pallets, etc.

Equipment Introduction:

The double-shaft shredder cuts and tears materials into smaller sizes through the shearing and tearing action of the blades during their relative rotation, which facilitates subsequent processing or achieves the purpose of volume reduction.

Thanks to its structural form and low-speed rotation, the twin-shaft shredder is characterized by high torque, strong shearing force, high processing capacity, good stability, and low noise.

Therefore, it is widely used in the field of solid waste treatment and can meet the recycling and reuse processing needs of various types of solid waste.

Application Range:

Industrial waste tires, ceramic or glass products, leather and textile scraps, defective plastic products, defective electronic products, waste wood, waste paper, waste slag, waste materials, waste packaging, etc., and non-metallic waste.

Domestic waste large items such as computers, refrigerators, washing machines, sofas, mattresses, disposable food containers, chopsticks, waste paper, plastic, and other metal or non-metallic waste

Bulk waste disposable food containers, chopsticks, beverage bottles, waste paper, plastics, and other metallic or non-metallic waste materials

Agricultural waste straw, tree branches, bamboo, animal carcasses, plastic mulch, etc.

Construction waste construction wood forms, old doors and windows, gypsum boards, drop ceilings, color steel tiles, etc.

Medical waste syringe waste, pharmaceutical waste, small medical equipment, used masks, surgical gowns, bed linen, and other medical waste.

Technical Highlights:

1 - Bearing life is long

Multiple protective measures are taken to extend the service life of the bearings

2 - Low crushing resistance

Different blade profile designs are selected according to the requirements of the crushed materials to minimize crushing resistance as much as possible.

3 - High crushing efficiency

The specially designed fixed knife not only serves as a material rejection function but also forms additional shearing with the moving knife, enhancing the overall crushing efficiency Working Principle

A double-shaft shredder utilizes two parallel, counter-rotating shafts equipped with interlocking blades to shear, tear, and crush materials.

When fed into the chamber, bulky waste is gripped and shredded between the rotating blades, which slice, rip, and compress it into smaller fragments.

The slow-speed, high-torque design efficiently processes tough materials (e.g., metals, rubber) and features auto-reverse anti-jamming protection.

Double-Shaft Shredder vs.

Single-Shaft Shredder

Double-Shaft Shredder: Features two counter-rotating shafts with interlocking blades, utilizing shearing, tearing, and crushing forces for high-volume or mixed waste processing.

Single-Shaft Shredder: Equipped with one rotor and stationary blades, designed for controlled size reduction of uniform materials at medium speeds.

5 Competitive Advantages

Double-Shaft Shredder Heavy-Duty Processing: Hydraulic system crushes metals, alloys, and mixed industrial waste.

Anti-Jamming: Auto-reverse function protects against overload.

Low Maintenance: Modular blades allow individual replacement.

Screen-Free Design: Output size adjusted via blade spacing.

High Throughput: Continuous processing capacity up to 3-20 tons/hour.

Single-Shaft Shredder Precision Shredding: Screen-controlled output for recycling granules.

Quiet Operation: Noise levels below 75dB (ideal for indoor use).

Energy Savings: 15%-30% lower power consumption vs dual-shaft.

Compact Footprint: 40% smaller space requirement.

Cost-Effecti ve: 50%-70% lower upfront investment.

FAQ

Q: Can a double-shaft replace a single-shaft shredder?

→ Not recommended.

Single-shaft units remain superior for fine plastic shredding with lower OPEX.

Q: How to select blade material?

→ Dual-shaft: Cr12MoV alloy steel (impact-resistant).

Singl e-shaft: SKD-11 tool steel (wear-resistant).
