What is the difference between the double-shaft Shredder and the traditional shredder? What are the characteristics? 

The double-shaft shredder's Knife roller structure includes a main shaft, a sleeve, a Blade, and several Blades arranged on the main shaft. The blade structure is a knife body and at least 2 to 6 claws arranged on the knife body. The edge of the knife body is provided with grooves to form a knife body working surface with a high-low surface structure. The surface where the blade edge contacts the material is a smooth circular cross-section. The knife roller of this structure will not be squeezed with the material during the crushing process, ensuring efficient Shredding and shearing effect.

Compared with the traditional shredder, the double-shaft shredder has more reasonable Knives. During the material shearing process, the new double-shaft shredder's knife roller will not cause the blade and the material to slip and squeeze, and the crushing efficiency will be low. The specific technical features include: 

1. The blade of the double-shaft shredder claw forms a knife county angle of 5°-30° with the axis of the main shaft. The groove extends along the axis of the knife body and runs through the entire knife body working surface. The groove is evenly distributed around the circumference on the edge of the knife body. 

2. When the number of blades is greater than one, sleeves are provided between adjacent blades of the double-shaft shredder to block the gap between the knives and ensure the interference fit between the spacer and the main shaft. The thickness of the spacer reaches 35mm~45mm at the same time. 

3. The claws of several blades on the main shaft are misaligned, and the claws are evenly distributed on the main shaft. The knife body is provided with a knife body inner hole with the knife body axis as the central axis. The knife body hole is a polygonal structure, mostly hexagonal. The knife body hole and the shredder main shaft are perfectly matched, with a tolerance of less than 0.1 mm. At the same time, the blade and the main shaft are tightly sleeved before welding. The interference fit between the spacer and the main shaft is conducive to the discharge of materials during the crushing process and enhances the strength of the main shaft. The arrangement structure of the staggered arrangement of the claws on the main shaft reduces the crushing impact force, reduces the idle time of the knife roller, and improves the current stability. The interference fit between the blade and the main shaft makes the blade and the main shaft an integral whole, reducing the possibility of cracks in the weld.The notable feature of the new double-shaft shredder is that the working surface of the tool adopts a concave and convex surface structure. Compared with the traditional flat surface structure, it greatly increases the resistance between the blade and the material, can actively clamp the material, drive the material to be broken, and improve the material shredding efficiency.
