The utility model discloses a plastic extruder capable of separating metal impurities in plastic particles, which comprises an extruder main body and a first motor, a screw propulsion rod is arranged in the extruder main body, a separation box is fixedly arranged at the outer end of the top of the extruder main body, a second motor is fixedly arranged on one side of the separation box, and the second motor is connected with the screw propulsion rod. And a second rotating rod is arranged in the separation box, a magnetic separation cylinder is fixedly arranged at the outer end of the second rotating rod, a communicating opening is formed in the front end of the separation box, and a scraper blade is fixedly arranged in the communicating opening. Metal impurities in plastic particles are separated out by arranging the magnetic separation cylinder, so that plastic entering the extruder main body does not contain the metal impurities, the condition that the inner wall of the extruder main body is abraded by the m
