The materials of this project mainly come from various types of hard materials/general hard plastics such as waste electronic and electrical mixed plastics, small household appliance plastics, car battery casings, etc. The crushing system adopts a wear-resistant design to ensure the continuous operation of the crushing system. The system took a long time. The separation principle of different densities is used to separate high-purity PS and ABS materials. The full-line automated control and the associated operation of each unit of the system maximize the production capacity and have the ability to predict possible abnormal situations, ensuring system safety to the greatest extent and efficiently washing electronic waste plastics.
