2. Working principle
When working, the material enters the shredding box through the feeding system. In the box, the shredding blade group begins to work. The material will be subjected to the combined forces of tearing, squeezing and shearing by the blades. Taking the double-shaft shredder as an example, multiple blades are installed on two relatively rotating knife shafts with different rotation speeds. This differential design generates strong shearing and tearing forces between the blades, which gradually shreds the metal materials like scissors. At the same time, during the shredding process, the blades will also squeeze the material to further crush the material. After this series of treatments, the material is torn into small pieces and discharged from the bottom of the box, completing the entire shredding process.

3. Advantages
1. Powerful crushing ability: Metal shredders can easily handle various types of metals, whether it is thin metal sheets, such as cans, iron sheets, etc., or metal parts with a certain thickness and strength, such as car shells, scrap steel, etc., can be efficiently shredded. Its powerful crushing ability comes from the carefully designed blade structure and powerful power system, ensuring that when facing metal materials of different materials and shapes, it can stably and efficiently complete the crushing task. ​

2. High operating efficiency: The equipment can maintain a high output during operation to meet the needs of production of different scales. The optimized design and advanced power system enable the metal shredder to process a large amount of materials per unit time. For example, some large metal shredders can process several tons or even more per hour, which greatly improves production efficiency and reduces production costs. ​

3. Durable and stable: The use of high-quality materials and advanced manufacturing processes makes the metal shredder have excellent durability. For example, the load-bearing box is welded with ultra-thick steel plates. After a special heat treatment process, the strength and toughness of the box are enhanced, and it can withstand long-term, high-load working pressure. The blade has been forged, precision-processed and heat-treated for many times, making its hardness and wear resistance reach extremely high levels, greatly extending the service life of the blade. In addition, the equipment is designed with full consideration of stability. Through reasonable structural layout and shock-absorbing measures, the noise and vibration during the operation of the equipment are reduced, ensuring that the equipment can operate stably for a long time. ​

4. Intelligent and easy to operate: Equipped with an advanced PLC automatic control system, the operator only needs to set the relevant parameters on the console, and the equipment can automatically run according to the preset program. The system also has an overload protection function. When the equipment encounters an overload situation, it can automatically shut down to avoid equipment damage, and at the same time issue an alarm to prompt the operator. In addition, the metal shredder adopts a modular design, and each component is independent of each other, which is easy to maintain and replace. Users can easily upgrade or replace the components of the equipment according to actual needs, which improves the flexibility and scalability of the equipment. ​

5. Environmental protection and energy saving: In terms of environmental protection, the metal shredder adopts a fully sealed structure and is equipped with a negative pressure dust removal device, which can effectively suppress the generation and diffusion of dust, realize dust-free operation, and reduce the harm to the working environment and the health of operators. In terms of energy saving, by optimizing the power system and equipment operating parameters, the energy consumption of the equipment is reduced, the energy utilization efficiency is improved, and it meets the requirements of today's society for energy saving and environmental protection.

IV. Classification
1. Double-axis shredder: This is the most common type of metal shredder. The two knife shafts rotate relative to each other, and the materials are shredded by the interaction of the blades. It has the characteristics of compact structure and strong crushing force, and is suitable for processing various metal materials of medium hardness and thickness, such as waste home appliance shells, metal pipes, small metal components, etc. The double-axis shredder can quickly shred these materials into suitable sizes, providing convenience for subsequent recycling and processing. ​

2. Single-axis shredder: The single-axis shredder has a main rotating shaft with multiple blades or hammers installed on the shaft. It is characterized by simple structure and easy operation, and is suitable for processing some relatively soft and thin metal materials, such as waste cables, cans, aluminum foil, etc. When processing these materials, the single-axis shredder can quickly decompose the materials into small pieces through the cutting and shredding action of the rotating blade, and has a high processing efficiency.

V. Application
1. Metal recycling industry: Metal shredder is the core equipment in the field of metal recycling. It can effectively shred various scrap metals, such as scrap steel, scrap aluminum, scrap copper, etc., into small pieces that are easy to transport and reprocess. The shredded metal materials can improve the recycling rate, reduce the recycling cost, and create greater economic benefits for metal recycling companies. For example, scrap steel processed by the metal shredder can more conveniently enter the steelmaking furnace for smelting, improving the efficiency and quality of steelmaking. ​

2. Processing of waste home appliances: With the continuous advancement of science and technology, the number of waste home appliances is increasing. Metal shredders can shred metal parts in waste refrigerators, televisions, washing machines and other home appliances to achieve resource recycling. During the processing process, the metal shredder shreds the metal casing, internal metal structural parts, etc. in the home appliances into small pieces, and then separates different types of metals through subsequent sorting processes for recycling. This not only reduces the pollution of waste home appliances to the environment, but also provides an important source of raw materials for the home appliance industry.​

3. Dismantling of scrapped cars: scrapped cars contain a large amount of metal materials, such as body steel, engine parts, aluminum alloy wheels, etc. Metal shredders play an important role in the dismantling of scrapped cars. They can tear large metal parts such as car shells and frames into small pieces that are easy to transport and handle. The shredded metal materials can be directly sent to steel mills or non-ferrous metal smelters for reprocessing to achieve resource recycling, and at the same time help reduce the occupation and pollution of scrapped cars to the environment. ​

4. Processing of industrial scraps: In the process of industrial production, a large amount of metal scraps will be generated. If these scraps are not properly processed, they will not only take up a lot of space, but also cause waste of resources. Metal shredders can shred these industrial scraps, such as metal sheet scraps, metal waste left over from mechanical processing, etc., and make them available again. By recycling industrial scraps, enterprises can reduce production costs, improve resource utilization efficiency, and achieve sustainable development.​

Metal shredders have become an indispensable and important equipment in the field of metal recycling and resource recycling due to their unique structural design, efficient working principle, excellent performance advantages and wide application fields. In the future, with the continuous improvement of environmental awareness and the continuous growth of demand for resource recycling, metal shredders will continue to innovate and develop, and play a greater role in promoting green development and building a beautiful home.
