A single shaft shredder is designed for coarse shredding, volume reduction, and recycling preparation of plastics and industrial solid waste. The machine uses a single cutting rotor together with a hydraulic pusher. The pusher continuously moves the material toward the rotating rotor, where rotary knives and fixed knives cut, tear, and compress the material.
The Haoxing Machinery single shaft shredder is suitable for plastic lumps, thick-walled plastic pipes, plastic pallets, injection molding waste, plastic film, woven bags, rubber, wood, wires and cables, and general industrial waste. The rotor design, knife material, screen opening, motor power, and pushing system can be selected according to the material size, hardness, bulk density, and required output size.
Unlike many double shaft shredders, a single shaft shredder is equipped with a screen beneath the rotor. The screen helps control the final output size and makes the machine suitable for recycling processes that require more consistent material dimensions. The shredded material can be transferred to washing, sorting, granulating, compacting, or other downstream equipment.
The modular construction provides convenient access to the cutting chamber, knives, and screen. The control system adjusts the hydraulic pusher according to the rotor load. If an overload occurs, the pusher can stop or retract, while the rotor can reverse before restarting.
After entering the cutting chamber, the material falls between the rotor and the hydraulic pusher. The pusher moves forward according to the programmed sequence and forces the material into contact with the rotating rotor.The rotary knives installed on the rotor work against the fixed knives mounted on the machine frame. As the rotor turns, the knives grip, cut, tear, and compress the material. The hydraulic pusher maintains feeding pressure, which is particularly useful when processing bulky, irregular, hollow, or low-density materials.
The shredded material falls toward the screen beneath the rotor. Material smaller than the screen opening passes through and is discharged. Oversized pieces remain inside the cutting chamber and continue to be processed until they reach the required size.
During operation, the control system monitors the main motor load. When the load exceeds the preset level, the hydraulic pusher stops or retracts. The rotor may also reverse briefly to release the material. Normal operation resumes after the load returns to an acceptable level. This process helps protect the motor, gearbox, rotor, and cutting knives.
The basic working process is:
Material Feeding → Hydraulic Pushing → Rotor Gripping → Cutting and Tearing → Screen Sizing → Material Discharge
The motor and gearbox drive the rotor at a relatively low speed while providing high torque. This design is suitable for bulky, irregular, and tough plastic or industrial waste. Low-speed operation also helps reduce dust, noise, and material ejection.
The hydraulic pusher automatically adjusts its movement according to the main motor load. The pushing system keeps the material in contact with the rotor and reduces bridging or idle rotation when processing plastic film, woven bags, plastic lumps, and hollow products.
A removable screen is installed beneath the rotor. Different screen openings can be selected according to downstream processing requirements. Oversized pieces remain in the cutting chamber until they are small enough to pass through the screen.
The rotary knives and fixed knives are removable. Worn knives can be replaced, sharpened, or repositioned. Different knife materials and surface treatments are available for materials with different hardness and wear characteristics.
The control system monitors the motor current and rotor load. If an overload occurs, the machine can stop or retract the hydraulic pusher and reverse the rotor. This reduces impact on the drive system and helps clear temporary material blockages.
The machine can process plastic lumps, pipes, pallets, film, woven bags, rubber, wood, wires and cables, and general industrial solid waste. The rotor, knives, screen, and drive system can be configured for different materials.
The cutting chamber, screen, and knife area are designed for routine inspection and maintenance. The hydraulic, electrical, and transmission systems are arranged separately to simplify servicing and replacement of wear parts.
The hopper size, rotor length, knife quantity, motor power, screen opening, feeding method, and discharge conveyor can be customized according to the feed size, required capacity, material characteristics, and output requirements.
Parameter description diagram for Single Shaft Shredder for Plastic and Industrial Waste | Haoxing Machinery:
The following data represents common reference configurations. Final specifications may vary according to the processed material, knife design, screen opening, and project requirements.
Capacity figures are reference values and vary significantly depending on the processed material.
The capacity for plastic film, woven bags, and hollow plastic products should be evaluated according to the material bulk density.
Thick-walled pipes, plastic lumps, and engineering plastics may require higher motor power and a reinforced knife configuration.
The actual output size is affected by the screen opening, material toughness, knife condition, and knife clearance.
Machine selection should consider the feed size, individual piece weight, material hardness, contaminants, and downstream processing requirements rather than motor power alone.
The single shaft shredder can be used for coarse shredding, volume reduction, and recycling preparation of the following materials:
Plastic lumps, injection molding waste, plastic pallets, crates, drums, sheets, thick-walled plastic pipes, PE pipes, PP pipes, plastic film, woven bags, and other plastic products.
General rubber products, rubber production scraps, fiber-reinforced plastics, and selected composite packaging materials. Materials containing a large amount of metal should be evaluated before processing.
Wood boards, wood blocks, wooden pallets, packaging boxes, cardboard, paper cores, and production offcuts.
Waste wires, cable coverings, and wiring harnesses before sorting, copper recovery, or copper-plastic separation.
Production scraps, packaging waste, lightweight industrial waste, and other solid materials that require controlled output dimensions.
The single shaft shredder is mainly used for coarse shredding, volume reduction, and recycling preparation. Materials containing heavy steel parts, large metal pieces, or hard foreign objects should be sorted before feeding or processed with a more suitable metal shredding system.

The reference capacity of the single shaft shredder ranges from 300 kg/h to 5 t/h. The actual capacity depends on the material type, feeding size, bulk density, cutter configuration, screen opening, feeding method and motor power.
The machine can be equipped with overload protection and an automatic reverse function. When the load becomes too high or material causes a blockage, the control system can stop or reverse the rotor to release the material, reduce jamming and protect the cutters, rotor, reducer and drive system.
Yes. The output size is mainly controlled by the screen opening and is also affected by the cutter structure, rotor speed, feeding amount and material characteristics. Different screens can be selected according to the requirements of downstream washing, sorting, pelletizing or other processes.
A single shaft shredder is suitable for plastic pipes, plastic drums, plastic sheets, film bundles, woven bags, waste drip irrigation tape, wood, pallets, cardboard and other recyclable materials. The machine configuration should be selected according to the material hardness, size, shape and contamination level.
Yes. The single shaft shredder can reduce waste polyethylene drip irrigation tape into smaller flakes for subsequent washing, dewatering, pelletizing or recycling. The cutter and screen configurations should be selected according to the dirt content, degree of entanglement and required output size.
Yes. The single shaft shredder can be equipped with a diesel engine or an electric motor according to the working site and available power supply. The diesel-powered configuration is suitable for sites with limited electricity, mobile operations or temporary material processing.
