You have piles of waste – plastic drums, old tires, scrap wood, electronic boards, and rubber. You need to reduce them into smaller pieces for recycling or disposal. But some materials are too tough for a normal crusher. A dual shaft shredder machine is built exactly for this job. It uses two counter-rotating shafts with heavy blades to tear, cut, and shred thick, hard, or sticky materials without jamming.
The YG twin shaft shredder is designed for industrial recycling. It handles electronic waste, plastic, metal, wood, rubber, packaging barrels, pallets, cables, PET bottles, cardboard, circuit boards, and more. After shredding, the material can be directly recycled or further processed. Key features include low speed, high torque, PLC automatic control, overload reverse protection, and durable blades made from special alloy steel.

What Materials Can A Dual Shaft Shredder Machine Process?
- Plastics and rubber – plastic drums, plastic scraps, PET bottles, rubber, tires, plastic pipes, plastic sheets, plastic buckets
- Wood and paper – wood, pallets, wooden furniture, paper, cardboard, fiber
- Metal – thin metal sheets, aluminum, cables, electronic waste
- Other waste – industrial waste, medical waste, municipal solid waste, packaging barrels, large rolls of film, thick and hard materials
After shredding, the output material can be directly recycled or further refined with a granulator, depending on your needs.
Key Features Of A YG Twin Shaft Shredder
- Handles large, bulky input – Big blocks, baskets, pipes, logs, tires, and large film rolls can be fed directly. No pre-cutting needed.
- Strong construction – Heavy-duty, thick steel plate frame, precision-machined. Large-angle hexagonal rotating shaft. Large, strong feed hopper. You can safely drop heavy materials.
- Heavy blades, high efficiency – Thick, heavy blades made from special alloy steel casting. Long service life.
- PLC automatic control – The machine has start, stop, reverse, and overload automatic reverse functions. If too much material jams the machine, it reverses automatically to clear the jam, then continues. This protects the motor and the cutting chamber.
- Low speed, high torque – Unlike a high-speed grinder, a dual shaft shredder runs slowly but with tremendous twisting force. This means low noise, low dust (meets environmental standards), and no shaft wrapping or jamming even with sticky or fibrous materials.
- Independent dual-shaft drive – Each shaft has its own motor and reducer. The shafts rotate at different speeds or in opposite directions, creating a pulling and tearing action that feeds material automatically
- No shaft wrapping – The unique blade structure and four-corner rotating knives prevent long strips of plastic or film from wrapping around the shafts.
How Does A Dual Shaft Shredder Machine Work?
Step 1 – Loading – You feed material into the large hopper. The hopper is wide and strong, so you can drop big items like a plastic drum or a wooden pallet.
Step 2 – Shredding – Two independent motors drive two shafts with cutting knives. The shafts rotate at low speed but with high torque. One shaft may turn slightly faster than the other, creating a shearing and tearing action. When the material enters, the hooked blades pull it down and cut it between the moving knives and fixed knives.
Step 3 – Automatic feeding – Because the two shafts work together, they automatically pull material into the cutting zone. You do not need to force-feed.
Step 4 – Jam protection – If too much material enters at once, the PLC controller detects overload. It automatically reverses the shafts to clear the jam, then resumes forward rotation. This prevents damage.
Step 5 – Discharge – Shredded pieces fall through the bottom of the machine. You can put a conveyor belt under it to carry the output to a granulator or collection bin.
The entire process is continuous and low-dust.

Common Questions Buyers Ask
1 year.
The blades (knives). Also, the spacers and isolation plates may wear over time, but blades are the main consumables.
It depends on the material. For shredding tires, blades can last 3-4 years. For harder materials, life is shorter. You can also order replacement blades from YG.
Yes. YG can customize blade dimensions according to your required output particle size.
Yes – after purchase, YG provides both.
