Application Industry

The metal shredder is widely used in scrap metal recycling, metal smelting, metal processing and reuse fields, steel mills, steel casting mills and other related industries.

Product introduction

Product introduction
Metal shredder is a professional equipment for coarsely crushing of various large-volume, high-hardness scrap steel and aluminum, which is commonly used in scrap metal recycling, metal scrap treatment, metal processing industry and abandoned vehicle processing. Metal shredder is mainly composed of shredding blade group, bearing box, frame, feeding system, power system and electrical control system. It is mainly used for shredding light and thin metals with certain strength to increase their packing density so as to facilitate transportation and recycling. Shredded objects include metal barrels, refrigerators, automobiles, waste steel, steel furniture, etc.



  • Metal shredder is suitable for a variety of materials. The metal shredder can shred various waste steel bars, metals, metal pressing blocks, metal impurities and other materials and so on.
  • The metal shredder also has the advantages of large shredding ratio, high production efficiency and small discharge particle size. 
  • Large torque, high output, low noise and wear resistance.
  • The machine is controlled by a PC system. The knife can be rotated in opposite direction and also can close automatically if something unexpected happens, with very high safety service.
  • The knife material is made of alloy steel with high quality and a long lifetime.
  • Low speed, low noise, and little dust.

Working principle

The metal shredder shears, extrudes and tears large metal materials or large-size metal materials which are inconvenient to transport into strip and block materials that meet the requirements. The material enters the inside of the shredding box body through the feeding system. The box body is equipped with shredding knife rollers. The material is shredded into small pieces by the comprehensive actions of mutual tearing, extrusion and shearing of the two knife rollers, which are discharged from the discharge port at the lower part of the box body.
