The invention relates to the technical field of tea processing equipment, in particular to a rolling and powder screening integrated device for tea processing. The device comprises a fixed plate, a roller, a rolling groove, sieve holes, a fixed block, a spring, an upright post, a mounting plate, a rotating shaft, a motor, a rolling disc and an adjusting mechanism, wherein the diameter of the rolling disc is not smaller than the radius of the rolling groove. The device has the beneficial effects that tea leaves in the rolling groove are rolled through the rolling disc; in the rolling process, due to the fact that a cam mechanism is formed by the rotating shaft and the rolling disc, the circumferential face of the rolling disc drives the rolling groove to swing on the fixed plate along the circumference; or the rolling groove forms a sieve mechanism, and tea powder in the tea leaf rolling process falls onto the fixed plate through the sieve holes, so that separation and sieving of the tea leaves and the tea powder are realized, workers are not required for sieving, the labor intensity of the workers is reduced, and the working efficiency is improved.
