Large Dual-Shaft Shredder for Scrap Tire Crushing

Working Principle:

The dual-shaft shredder employs independent dual-shaft drive, which generates corresponding compression on the material during production, achieving automatic feeding. The blade shaft structure and four-corner rotary blades ensure that during the low-speed, high-torque production process, there is no shaft entanglement or equipment jamming, thereby improving production efficiency. This equipment is suitable for shredding various materials with high toughness and viscosity. The dual-shaft shredder can meet various waste recycling requirements and is ideal for shredding thick, hard-to-break materials such as electronic waste, plastics, metals, wood, used rubber, packaging barrels, and pallets. It can handle a wide variety of recyclable materials, and the shredded output can be directly reused or further refined as needed. It is applicable in industries such as industrial waste recycling, electronics manufacturing, pallet manufacturing, wood processing, plastic recycling, tire recycling, and papermaking.

Advantages of the Dual-Shaft Shredder Equipment:

1. This equipment can crush large metal blocks, basket materials, pipes, plates, wood, tires, and large rolls of film that are difficult for single-shaft shredders to process;
2. The outer frame is a precision-machined combination structure made of extra-thick plates, featuring a high-strength rotating shaft with a large-angle hexagonal column and a large-diameter, sturdy feed hopper, allowing for the safe feeding of large raw materials;
3. The rotary blades are designed and processed in terms of thickness, shape, and arrangement sequence, offering strong shear force and sharp edges for powerful crushing;
4. Equipped with PLC control, it includes forward and reverse rotation and shutdown functions to protect the machine when processing oversized or excessive materials;
5. Low-speed operation ensures low noise and minimal dust;
6. The blades are made of special alloy steel, ensuring durability and a long service life.

Different names such as metal shredder, plastic shredder, and tire shredder refer to customized shredder equipment designed by manufacturers based on the materials customers need to process. These designs include targeted adjustments and blade cutting methods to meet customer requirements and maximize their benefits. Different models correspond to variations in size.


The dual-shaft crusher is driven by an electric motor or hydraulic motor, with blades made of special alloy steel and controlled by a programmable logic controller. It can automatically reverse when encountering hard objects, and the output size can be designed according to user requirements. The blade shaft speed typically ranges from 10 to 70 revolutions per minute, with the high speed of the motor reduced to the low speed of the blade shaft via a gear reducer. As a result, the low-speed dual-shaft crusher features high torque, energy efficiency, low noise, and low dust emissions.
