Engineering plastics have excellent comprehensive properties, high rigidity, low creep, high mechanical strength, good heat resistance, good electrical insulation, and can be used for a long time in harsh chemical and physical environments. They can replace metals as engineering structural materials, but they are more expensive and have lower output. Alloy engineering plastics are also a type of engineering plastics. When processing alloy engineering plastics, they need to be pelletized. After pelletizing, the particles need to be screened. Therefore, a multi-layer screening device for alloy engineering plastic particles is needed.
