With the development of global industrialization and urbanization, environmental issues have caused full attention. In the process of urbanization, urban garbage has sounded the alarm. According to different sources of garbage generation, urban garbage can be mainly divided into three categories: domestic garbage, street cleaning garbage, and group (organization, school, factory, and service) garbage. Cities with developed economies and higher living standards have higher organic content. In coal-dominated cities, coal slag and sand and gravel account for a larger share of waste.
  The waste shredder machine can greatly reduce the manual sorting workload. When handling urban domestic waste, the bag breaking process can be omitted, manual sorting can be reduced, the waste processing process can be shortened, and investment can be saved. The waste shredder machine operates safely and reliably. It integrates multiple functions such as automatic bag breaking, automatic sorting of hard objects, shredding, and crushing. It is a key device in the waste pretreatment process.
  In the treatment process of domestic garbage, for the convenience of sorting, multiple crushing treatments are required. The former crushing is performed by a coarse crusher or a biaxial shearing crusher, and the fine crushing is completed by a biaxial crusher. It is worth noting that the coarse crusher and the twin-shaft crusher can crush metals and stones, but the twin-shaft crusher is only suitable for plastic, paper, rubber, organic matter, etc. sorted from domestic waste.
  The waste shredder machine is carefully developed using the theories of impact, shear, mutual impact, and grinding. When the waste shredder machine is working, the material can be fully and effectively finely crushed in the crushing cavity, with high output, low energy consumption, and efficiency. High, fine and uniform discharge, and when using this equipment, low noise, no pollution, simple operation and convenient maintenance.
