The invention relates to the field of twin-screw extruders, and discloses a twin-screw extruder comprising a mounting plate, on the top surface of which a twin-screw extruder body is detachably arranged. A plurality of loading and unloading grooves are formed on the top surface of the twin-screw extruder body, and detachable loading and unloading folding plates are arranged inside the grooves. A storage groove is formed on the inner bottom surface of the leftmost loading and unloading groove, with communication holes on both sides inside the storage groove. A replaceable circular plate is detachably arranged in the storage groove, and a plurality of extrusion holes are formed on one side of the replaceable circular plate. An addition hole is formed on the top surface of the twin-screw extruder body, and an arc-shaped plate is fixed on one side of the extruder body. In the invention, the replaceable circular plate in the original storage groove can be taken out and replaced, so as to change the diameter of the extrusion holes, further control the diameter of the finished flame-retardant masterbatch, and expand the application scope of the twin-screw extruder body in producing flame-retardant masterbatch.
