Name:Double-Shaft Shredder
Raw materials:Waste cars, used tires, electronic waste, wooden pallets, plastic drums, refrigerators, and other bulky industrial or municipal solid waste.
Application:Primary size reduction in scrap yards, recycling plants, and waste-to-energy facilities. Low-speed, high-torque shearing action safely processes hazardous and flammable materials with minimal dust, noise, and spark risk.
01 — Project introduction
Double-Shaft Shredder — Built for the Messiest Waste Streams
The double-shaft shredder is designed to handle a wide range of waste streams with very different material properties — from scrapped cars, used tires, and electronic waste to wooden pallets, plastic drums, refrigerators, and bulky municipal solid waste. Two counter-rotating shafts run at low speed and high torque, using shearing rather than impact to break down the feedstock. This low-RPM shearing action minimizes dust, noise, and sparks, making the unit especially suitable for hazardous or flammable waste where ignition risk must be kept to a minimum.
The blade geometry is fully customizable to match the processed material. Depending on the application, the rotor can be fitted with V-shape teeth, hook cutters, flat blades, or a combination, and the blade thickness, diameter, and tooth count are engineered to the required throughput and final flake size. A single machine platform can therefore serve as a coarse shredder for metals, a size-reduction stage for plastics, or a pre-shredder for downstream separation lines.
A spacing comb mounted between the blades and connected to the inner wall of the shredder chamber plays a critical supporting role. It prevents fibrous and flexible materials from wrapping around the shafts, guides the feed into the shearing zone, and enforces a controlled discharge size. The result is a cleaner cut, more uniform flakes, and lower wear on the rotor bearings and drive system — translating into higher uptime and lower operating cost for the operator

03 — Technical characteristics
ngineered Details That Pay Off at Runtime
  • Up-down opening bearing housing — direct top access to bearings and rotor for fast, tool-light maintenance that slashes downtime.
  • Independent control cabinet with Siemens PLC — centralized, intuitive operation and seamless integration with upstream/downstream equipment.
  • Built-in damper — smooths feed surges and material fluctuations, stabilizing both the process and the downstream product size.
  • Planetary gear reducer — high transmission efficiency, compact footprint, and proven stability under continuous heavy-duty operation.
  • High speed, large torque, low noise — tackles the toughest shredding workloads while keeping the work environment operator-friendly.
04 — Advantages
Built to Last, Designed to Run
  1. 42CrMo high-alloy cutting knives — Every cutting knife is forged from 42CrMo high-alloy steel, delivering the strength and toughness required for sustained heavy-duty shredding and long service intervals.
  2. D2 tool-steel blades for D- and DM-rotors — Both rotor options pair D2 tool steel (cutting blade) with 42CrMo (supporting knife), matching the right material grade to your toughest applications.
  3. World-class electrical components — Main electricals are sourced from trusted brands such as Siemens and Schneider, ensuring long-term reliability and easy access to service parts worldwide.
  4. Smart auto-reverse protection — When the motor detects overload or material jam, the system automatically reverses the rotor to clear the obstruction, protecting the drive train and keeping your uptime intact.
  5. Optional hydraulic pusher ram — For hollow containers, bulky frames, and other low-density materials, an add-on pusher ram actively forces feed into the cutting chamber, holding throughput steady where gravity feeding would stall.

Built to Fit Your Application
Every shredder is built to match the job. Blade thickness and tooth count are selectable based on feedstock, desired flake size, and target throughput — so the cutting system is tuned to your material rather than the other way around.
For the DS380 and DS3120 models, rotor speed and motor power are also customizable to match your specific capacity and load profile, keeping the drive train properly matched rather than over- or under-sized.
Our engineers work with you on these parameters during quotation, so the unit arriving on site is ready to perform from day one.
Specifications are subject to change without prior notice as part of our continuous product improvement.
