Double shaft shredder, as a kind of efficient solid waste treatment equipment, the essence of its working principle lies in the skillful combination of double shaft shear and extrusion. When the material is fed into the inlet of the shredder, it will first encounter two intermeshing rotating shafts, the blades or teeth on these two shafts are designed to be extremely precise, and can be customized according to the characteristics and processing needs of different materials.
With the continuous rotation of the two shafts, multiple shear zones will be formed between the blades, and the material will be subjected to strong shear force in these zones, and begin to be gradually torn and crushed. At the same time, because the spacing between the twin shafts can be adjusted, so it can realize the precise control of the material particle size. During the shearing process, the material is also subjected to the squeezing force generated from the rotation of the twin shafts, which further promotes the crushing and refining of the material.
It is worth noting that the twin-shaft shredder is also equipped with a powerful power system during operation to ensure that the twin shafts can rotate continuously and stably. In addition, in order to cope with materials of different hardness and toughness, the shredder also adopts blades made of various materials, such as cemented carbide, high-speed steel, etc., so as to improve the wear resistance and service life of the blades.

The uniform distribution of torque is ensured through the use of splines and hexagonal shafts. As a result, this equipment has gained wide application in the field of recycling and processing of industrial waste, municipal solid waste and other comprehensive waste materials.
As the materials are continuously crushed and refined, they will eventually be discharged through the outlet of the shredder. At this point, the material has been processed into the required particle size, can be directly for subsequent processing or utilization.
Overall, the dual-shaft shredder through its unique dual-axis shear and extrusion working principle, to achieve efficient and accurate processing of various types of solid waste materials. It not only improves the efficiency and quality of material processing, but also reduces energy consumption and noise pollution in the process, making a positive contribution to the cause of environmental protection and sustainable development.
