With the increasing awareness of environmental protection, more and more people are beginning to engage in research on industrial waste reuse, and waste recycling has become a popular project in recent years. It is a resource recovery engineering technology that has developed in recent years with the development of the environmentally friendly energy production chain. It has become one of the important deep processing technologies for industrial minerals and other raw materials, and is of great significance for the industrial development of modern high-tech waste resource recycling production technology.

　　The traditional screening process used by copper rice machines requires water. When the crushed raw materials are put into water, the plastic will automatically float up and the metal will automatically sink, using buoyancy to screen out plastic and metal. The principle used by dry copper rice machines is sorting, which is specific gravity sorting, The production process of the copper rice machine production line is: waste wire and cable - primary crushing - vibration sorting machine - dust removal - secondary crushing - bucket elevator - high-voltage electrostatic sorting equipment - separation completed.
