The single-shaft shredder operates on a low-speed, high-torque shearing principle, featuring robust construction, smooth operation, and low noise.
It is engineered to meet the waste recycling needs of various industries and is capable of processing a wide range of materials such as plastics, paper, wood, fiber, rubber, and household garbage.
In plastic recycling plants, this machine particularly excels at handling post-consumer contaminated plastics (“social” scrap) as well as clean production scraps (“factory” off-cuts), demonstrating distinct advantages in both scenarios.
For contaminated and oily post-consumer waste, the shredder’s high-torque rotor and automatic reverse protection prevent jamming and damage, easily handling heterogeneous materials; for clean factory scraps, it can rapidly and efficiently shred sprues and off-cuts into uniform particles, enhancing the efficiency of downstream recycling processes
It uses a PLC program control system to automatically monitor the shredding process, featuring start, stop, reverse, and overload auto-reverse. This intelligent control enhances operational safety and reliability.
It is equipped with a high-strength alloy steel rotor (diameter up to 380 mm) to ensure ample cutting force. The rotary knives are made of wear-resistant material and have multiple cutting edges that can be rotated for extended use, and the fixed counter-knives are adjustable to maintain optimal blade clearance.
A built-in hydraulic pusher (with stroke up to 1000 mm) continuously presses material into the rotor, enabling automatic and even feeding.The hydraulic system features dual-speed control with an integrated oil cooler, allowing fast movement under no-load and slower, forceful feed under load, which boosts shredding efficiency while preventing blockages.Upon overload or foreign object detection, the system works with the PLC to instantly reverse, protecting the motor and gearbox from damage.
The machine features a compact and rational design, with a small footprint that allows flexible installation in plant layouts. Maintenance is user-friendly: the cutting chamber includes a large access door for quick cleaning of residuals; the blades and screen are designed for easy swap-out, allowing fast changes to different sizes without complicated disassembly, greatly reducing downtime.

In the field of plastic recycling, this single shaft plastic shredder can handle virtually all common waste plastic products and other solid wastes.
Typical uses include pre-shredding large hollow or thick materials into smaller sizes for subsequent granulation and washing. The main applicable materials include:
HDPE bottles； PET bottles； PE pipes； plastic films； PP woven bags； plastic barrels and crates； foam plastics, ABS/PS rigid plastic parts, waste appliance housings
By size-reducing the above materials with a single shaft shredder, their volume is greatly decreased, which facilitates subsequent conveying and recycling.
In addition, as a versatile single shaft waste shredder, it is also capable of coarse-shredding other waste like cardboard, wooden pallets, and textiles, providing broad applicability in solid waste recycling.
