Product overview
D series Double Shaft Shredder from United Tech Machinery is designed for a wide range of industrial applications. It shreds solid materials — e-waste, metal, wood, plastic, tires, pallets and bulky or contaminated items — to increase bulk density and reduce transport costs. The unit uses two low-speed, high-torque rotors and a PLC microcomputer control system with automatic start/stop and automatic reverse sensors for overload and jam protection.

Advantages

• Motor and rotor driven via reducer for low-speed, high-torque shredding.
• Sixfold enclosed bearing seals for waterproof and dustproof protection to extend bearing life.
• Repairable, reusable blades using advanced coating and welding to lower maintenance costs.
• Separated shredding chamber design allows full-shaft discharge (rotor, blade, bearing, sealing system) for maintenance.
• Spiral blade arrangement for consistent and effective shredding.
• Hexagon fit between blade inner hole and main rotor for blade stability and even force distribution.
• Multiple blade types available to match input material and required durability.

Cutting tools / Blade information
Blade type and geometry determine output particle size and characteristics.

• Rotor blade thickness affects particle width — thinner blades produce narrower particles.
• Distance or number of rotor blade tips affects particle length — closer spacing or more blades produce shorter particles.

Applications

• Metals: aluminum parts, motor housings, oil drums, vehicle scrap, ferrous waste, steel plates.
• Waste tires: passenger, truck and OTR tires.
• Plastics: drums, packaging cases, pallets, cans.
• Waste treatment: medical, hazardous, industrial and kitchen waste; animal carcasses.
• Electronic waste: refrigerators, TVs, washing machines, other e-waste.
• Secure disposal: hard drives, expired food, paper, medicines.

Specification / Notes

• Power supply voltage selectable per customer requirements.
• Shredding capacity depends on material composition and requested output size.
• Specifications are for reference and may change without prior notice.
