In the existing engineering plastic particle sorting production device, during the process of recycling engineering plastic particles, the engineering plastic particles are doped with metal fragments. Therefore, it is necessary to screen out the metal fragments before screening the engineering plastic particles. A separate set of screening metal fragments needs to be set up, which increases the production cost and floor space. Therefore, an engineering plastic particle sorting production device is proposed.
