Copper rice machines can be divided into dry type copper rice machines and wet type copper rice machines.
1. Dry type copper rice machine refers to a copper rice machine that does not need to add water during the sorting process. This type of copper rice machine mainly uses air flow sorting machines, air shakers or electrostatic sorting and other more environmentally friendly methods for sorting. The main process flow is: crushing - air flow separation - (electrostatic separation) - dust collection. (Electrostatic separation is rarely used in copper rice machines.)
2. Wet sorting of wet type copper rice machine is a relatively traditional method. The idea of this sorting method mainly comes from mineral processing. The wet type mainly uses gravity shaker sorting. The main process flow is: crushing and (adding water) - gravity shaker (adding water). Since water is used in the production process, in general this method causes a small amount of secondary pollution to the environment, but it can be effectively recycled. Miscellaneous wires, plug wires and wool wires, etc., are widely used.
