The invention relates to the technical field of limestone, and discloses modified limestone powder dry grinding and screening equipment. The equipment comprises a base, wherein the upper end of the base is movably connected with a dry grinding mechanism; the dry grinding mechanism comprises a shaft pipe; the shaft pipe is rotationally sleeved with an iron screen drum; the lower end of the shaft pipe is rotationally connected with a grinding roller extending to the inner wall of the iron screen drum; the position, at the upper end of the shaft pipe, of the front side of the iron screen drum is fixedly connected with a material box; and the front end of the iron screen drum is fixedly connected with a gear ring. According to the modified limestone powder dry grinding and screening equipment, the grinding roller is designed at the bottom of an inner cavity of the iron screen drum, an E-shaped rod is matched, the shaft pipe located at the upper side of the grinding roller is used for intermittent feeding, a convex half gear is used for driving the gear ring to rotate intermittently, an intermittent compression mechanism of a compression joint bag is matched, and then a knocking rod can knock the top of the iron screen drum intermittently, so that materials blocking sieve holes are vibrated off in time, the overall processing effect of the equipment is effectively improved, and the screening efficiency of the materials is guaranteed.
