Dual Shaft Shredder – Multi-Purpose Industrial Shredding Equipment

The SY Series Dual Shaft Shredder is a versatile industrial shredding machine designed for processing a wide range of materials including plastic, wood, paper, light metal, household appliances, rubber, and textile products. With heavy-duty construction and powerful shredding capability, this equipment is the ideal solution for waste recycling plants, material recovery facilities, and industrial processing operations.

The dual shaft design with alloy steel blades delivers high torque, low speed, and efficient shredding performance, handling everything from hard plastic blocks and metal scraps to bulky household appliances and rubber tires.

Applicable Materials

Category Specific Materials
Plastic PP/PE packing film, agricultural film, woven bags, drinking bottles, plastic pipes, plastic boards, plastic pallets, plastic lumps, plastic crates, hard plastic blocks (PP, PE, ABS, fiber glass, etc.)
Wood Wood timber, tree roots, wood pallets
Paper Newspapers, magazines, books, carton boxes
Light Metal Aluminum cans, aluminum scraps, aluminum blocks
Household Appliances TV sets, refrigerator bodies, plastic chairs, air conditioner bodies, washing machine bodies
Rubber Tires (car, truck, OTR tires)
Textile Products Cloth, fiber, carpet products

Working Principle

The dual shaft shredder operates on a low-speed, high-torque shearing principle. Two counter-rotating shafts equipped with interlocking alloy steel blades pull materials into the cutting chamber. The blades shear, tear, and crush materials against each other and the fixed counter-knives, reducing them to uniform particle sizes. The hydraulic or mechanical pusher ensures consistent material feeding, while the PLC control system monitors and adjusts operation for optimal performance and overload protection.
