Brief introduction

Double-shaft shredder, also known as shear shredder, reduces the size of materials by shearing, tearing and squeezing. This type of shredder is widely used in the shredding of waste plastics, waste rubber, wood and other large-volume waste. Our company has introduced more than 30 years of experience in manufacturing such equipment in Europe and the United States to China, and has improved, developed and launched a series of double-shaft shredders with mature technology and advanced design according to the actual domestic situation, providing reliable quality equipment for the crushing and volume reduction treatment of waste recycling in my country.

The thickness of the tool and the number of claws can be replaced according to different materials. When crushing hollow materials, a pressing device can be equipped to increase the output. A rotating screen can also be added to control the size of the discharge. When the double-shaft shredder runs at a low speed, the noise and dust can reach a higher environmental protection standard.

Performance advantages

1. The main body of the double-shaft shredder is made of high-quality steel plates as a whole, which ensures the stability of the equipment under long-term load.
2. The moving knife material is made of special alloy tool steel forging blanks, precision machining, multiple heat treatments and low-temperature freezing heat treatment technology to ensure cutting performance and service life. The fixed knife adopts professional hook installation, which optimizes the tool replacement function and makes tool maintenance and replacement more efficient.
3. The bearing seat of the double-axis shredder adopts a spliced ​​and easy-to-disassemble installation, which can quickly remove the moving knife, fixed knife, bearing and other components, easy to maintain and replace the knife, and the unique sealing structure effectively blocks the contact and pollution of metal debris and grease.
4. The knife shaft is made of high-strength and heavy-duty special steel, which is more reasonably matched with the knife, providing a strong guarantee for cutting and shredding.
5. The thickness of the double-axis shredder knife is divided into 15mm, 20mm, 40mm, 50mm, 75mm, and 100mm. The thickness of the knife and the number of claws can be replaced according to different materials.

Scope of application

The double-axis shredder is used to crush plastics, rubber, fiber, paper, wood, large hollow materials (plastic barrels and other large containers) and various mixed wastes, especially wastes containing metal, or pre-crushed wastes containing mud and sand that are easy to wear the knife. For example: rolled film, woven bags, TV, refrigerator shell, wood, car and medium-sized car tires and hollow barrels, fishing nets, cardboard, circuit boards, etc.

Working Principle

The material enters the shredding box through the feeding system. The box is equipped with shredding blades. The material is shredded into small pieces by the shredding blades, which are then discharged from the bottom of the box.
