Metal shredder is a kind of shredding equipment specially used to deal with metal materials, which is widely used in the recycling of scrap metal. It can tear large pieces of metal material into smaller sizes, which is convenient for subsequent processing and recycling. The following is the scope of application and working
principle of the metal shredder:
Application range of metal shredder:
Scrap cars: Metal parts such as shells, doors and frames of scrap cars can be shredded and processed into smaller pieces for subsequent metal separation and recycling.
Metal waste: suitable for processing all kinds of metal waste, such as iron sheet, aluminum products, scrap steel, copper wire, aluminum wire, scrap metal cans, metal bars and other metal products.
Appliance recycling: Used to shred metal parts of waste appliances (such as washing machines, refrigerators, air conditioners, etc.) to facilitate further separation of metals and other materials.
Electronic waste: Metal components in electronic waste can be processed, such as circuit boards, metal parts of electronic components, in order to recover valuable metals (such as copper, aluminum, gold, etc.).
Industrial metal scraps: widely used in the treatment of metal scraps and scraps produced in various industrial processes, reducing the volume for easy recovery and transportation.
Scrap metal barrels: can tear a variety of metal barrels, paint barrels, metal cans, steel containers, etc., to help recycle metal materials.
Working principle of metal shredder:
The working principle of the metal shredder is mainly to use a high-speed rotating blade to cut, tear, and extrude metal materials into small pieces or particles. The specific working principle is as follows:
Feed: The metal material to be treated enters the feed port of the shredder through the conveying device (such as conveyor belt) or by manual feeding.
Shredding process: there are two or more relatively rotating knife shafts inside the shredder, and each knife shaft is equipped with multiple blades. When the material enters the shredding chamber, the blade cuts, tears and squeezes the material by rotating it. The metal material is broken down into smaller pieces in the process of shearing and tearing.
Screening and separation: The material after shredding is discharged through the screen, and the size of the screen aperture determines the size of the final particle. Larger pieces continue to be shredded in the shredding chamber until they are small enough to pass through the screen.
Discharge: The material is discharged through the discharge port after reaching the required size. The shredded metal fragments can be further sorted, such as magnetic separation, eddy current separation, etc., to separate different types of metal and non-metallic materials.
Power and control system: Metal shredders are usually powered by electric motors or hydraulic systems. Modern metal shredders are usually equipped with automatic control systems that automatically adjust the shredding speed and blade clearance according to the type of material and the amount of feed, ensuring efficient and safe operation.
The design and blade material of the metal shredder determine the type and size of the metal it can handle, usually using high-wear and high-hardness alloy blades to ensure the efficiency and service life of the metal shredder. It plays an important role in the fields of scrap metal recycling, resource reuse and environmental protection treatment.
