The invention relates to a tobacco shred recovery system and a spiral waste cigarette crushing device thereof. Waste cigarettes are beaten by a beating module after entering an accommodating cavity to fall into an outer cylinder. Along with rotation of the outer cylinder, a concave-convex structure, formed on the inner wall of the outer cylinder, of a cigarette lifting module is collided with the falling waste cigarettes to raise up the waste cigarettes in the outer cylinder, and the waste cigarettes are fed in a beating area of the beating module again. Through multiple times of circulation, the waste cigarettes in the outer cylinder can be repeatedly beaten by the beating module for multiple times. Under guidance of a spiral guide piece, the waste cigarettes move from a feed port to a discharge port in a spiral path, so that the stop time of the waste cigarettes in the accommodating cavity is prolonged, and the beating times of the waste cigarettes can be further increased. Even if the rotating speed of the beating module is lower, the waste cigarettes can be sufficiently beaten through increasing effective beating times, so that tobacco shreds are thoroughly separated from cigarette papers. The tobacco shred recovery system and the spiral waste cigarette crushing device thereof can effectively increase the tobacco shred recovery rate.
