AbstractThe invention relates to a different-direction parallel double screw for a stone paper continuous internal mixing granulator. The different-direction parallel double screw comprises a screw I and a screw II which are arranged in parallel at an interval, and the screw I and the screw II are arranged in different directions on two sides of a center line between the screw I and the screw II in a mirror symmetry manner; the screw rod I comprises a mounting section I, a feeding section I, a first-section right-handed rotation internal mixing rotor, a right-handed rotation buffer section and a second-section right-handed rotation internal mixing rotor which are sequentially, adjacently and coaxially arranged from left to right; and the screw rod II comprises a mounting section II, a feeding section II, a first-section left-handed mixing rotor, a left-handed buffer section and a second-section left-handed mixing rotor which are sequentially, adjacently and coaxially arranged from left to right. According to the different-direction parallel double screw, two times of high extrusion and low shearing effects are achieved on the whole, and compared with a traditional parallel double-screw structure, shearing heat can be effectively reduced, and the raw material molecular chain structure can be effectively prevented from being damaged due to shearing overheating.
