Double Shaft Shredder – D Series

High‑torque primary shredding for bulky and tough materials.

Built for bulky feedstock

Handles large, tough, mixed materials with stable torque.

Simple, rugged drive train

Heavy‑duty drivetrain designed for harsh duty cycles.

Anti‑jamming control

Auto‑reverse logic to reduce downtime under overload.

Typical reply within 24–48 hours. Share material, throughput target, output size and destination country.

Engineered to stay stable under load

Not a “spec sheet machine”. We focus on real feedstock variability, stable throughput and maintainability.

High‑torque shredding

Designed for primary shredding where force matters.

Cutter profile selection

Choose cutter shapes for your material and target output.

Overload protection

Torque limiting + reversing logic to protect drivetrain.

Easy integration

Works with conveyors, feeding hoppers and downstream lines.

Built for real feedstock variety

Pick common materials below — we can tune knives, screens and options to match.

Plastic lumps

Purging, thick parts, bulky rigid plastics.

Tyres

Primary shredding to prepare for granulation.

Industrial waste

Mixed industrial waste and bulky scraps.

MSW / RDF

Pre‑processing for RDF and sorting lines.

Light metals

Light scrap for size reduction and sorting.

Wood & pallets

Bulky wood waste for logistics and downstream processing.

Common questions

How do I choose the right model?
Share your feedstock, throughput target, output size and site constraints. We will recommend a feasible model range and configuration.
Can output size be controlled?
Yes. Depending on the machine type, output is controlled by screen size and knife configuration, or by cutter profile and downstream secondary crushing.
What affects throughput the most?
Material type, feeding method, required output size, knife design and operating hours. Provide details and we will estimate a realistic range.
Do you support overseas delivery?
Yes. We ship globally and support overseas projects with remote and on‑site service depending on schedule and location.
What information do you need for a quote?
Material, throughput, output size, contamination/moisture, power/space constraints and destination country.

About the Double Shaft Shredder (D Series)

The SLECOTECH Double Shaft Shredder (D Series) is a heavy-duty, low-speed twin-shaft machine for the toughest heterogeneous feeds. Two intermeshing shaft sets shear material with high torque, making it ideal for dense, contaminated or entangled waste streams.

Key Applications

  • Tires and rubber
  • Drum and barrel scrap
  • Metal and plastic drums
  • Mixed industrial and demolition waste
  • Refrigerators and WEEE (with proper prep)

Technical Advantages

  • High-torque, low-speed shearing reduces dust, heat and spark risk
  • Intermeshing shaft geometry for aggressive bite on dense objects
  • Hard-faced, removable cutters for wear resistance
  • Auto-reverse and load-sensing protection
  • Robust welded frame for 24/7 operation

Frequently Asked Questions

What is the difference between double shaft and double rotor shredders?

Both use two rotors, but the D Series uses intermeshing shear shafts for dense, hard objects, while the T Series uses counter-rotating rotors for high-volume light waste. Pick D for toughness, T for throughput.

Can the D Series shred whole tires?

Yes – tires are a classic D Series application. For steel-belted truck tires, pre-cutting or a subsequent granulator improves downstream separation.

Is the D Series suitable for metal?

It handles light metal and drums, but thick solid steel should be avoided or pre-cut. Ferrous separation downstream is recommended to protect downstream equipment.

How are the cutters maintained?

Cutters are hard-faced and removable; worn segments are flipped or replaced without dismantling the whole shaft, keeping downtime short.
