The key to improving the efficiency and output of the aluminum-plastic separation production line lies in the pretreatment of materials and the precise sorting ability of the equipment. Reasonable pretreatment steps, such as cutting the composite material into appropriate sizes, can improve the sorting efficiency. At the same time, the use of high-performance grinding equipment and high-voltage electrostatic sorting devices can ensure a more thorough separation of aluminum and plastic. In addition, optimizing equipment parameters, such as sorting voltage and sorting speed, can also further improve efficiency and output.
