The invention discloses a junked tire liquid nitrogen cryogenic grinding box and a using method. The junked tire liquid nitrogen cryogenic grinding box comprises a box body, a feeding inlet, a sealingdoor, a connection rope, a sliding plate, two brackets, two rotation wheels, four stand bars, a discharging outlet, a sealing cover, a high-pressure liquid nitrogen cabin, a nitrogen pipe, an electromagnetic valve, a spray pipe, a spray head, a decompression cabin, a spring, a draught fan, a ring-shaped air duct, a jet head, an air exhaust slot, a sealing rubber rod and a bypass pipe, wherein thefour stand bars are uniformly mounted at the bottom of the box body; the feeding inlet is formed above the side wall of the box body; the bottom end of the feeding inlet is rotatably connected with the sealing door; the sliding plate is rotatably mounted on the inner wall of the box body and below the feeding inlet; the two brackets are symmetrically fixed on the inner wall of the box body and between the feeding inlet and the sliding plate; and the rotation wheels are rotatably mounted at the tops of the brackets. According to the junked tire liquid nitrogen cryogenic grinding box, rubber bricks are stirred through intermittently spraying liquid nitrogen and intermittently blowing air, so that the rubber brick grinding speed is improved, the liquid nitrogen is saved, and the putting andtaking of the rubber bricks are convenient, so that the junked tire liquid nitrogen cryogenic grinding box is simple in structure and safe to use.
