This utility model discloses a double planetary screw mixer with two-end support, relating to the technical field of slurry preparation. The mixer comprises a driving device including an input shaft system; a sun shaft system, the first end of which is connected with the input shaft system through gear engagement; a planetary shaft system including two planetary shafts, which are connected with the second end of the sun shaft system through gear engagement; a machine barrel; a mixing device including two parallel screws arranged in the machine barrel; a passive connecting seat arranged at the first end of the machine barrel, the first ends of the two screws pass through the passive connecting seat and are coaxially connected with the planetary shafts; a double planetary gear box, the sun shaft system is connected with the double planetary gear box through a key; and a passive transmission device, the second ends of the two screws are both connected with the passive transmission device. The device can solve the problems of intermittent production and differences between different batches of the existing double planetary mixers, and improve the problems of screw deflection and deformation and easy contact and wear with the barrel wall caused by the large length-diameter ratio of the twin-screw extruder.
