Rapid and efficient screening device for fine aggregate

The rapid and efficient screening device comprises a box body, a fine aggregate sliding way and a spiral feeder, the fine aggregate sliding way is communicated with the left side of the box body, the top end of the box body is communicated with a circulating feeding hopper, the lower end of the spiral feeder is communicated with the box body, the upper end of the spiral feeder is communicated with the circulating feeding hopper, and a fine aggregate window is formed in the inner wall of the box body. A fine material window is arranged in the box body, the fine material window is communicated with the fine material slide way, a filter screen is covered in the fine material window, a slapping mechanism is further arranged in the box body, the slapping mechanism slaps aggregate falling into the circulating feed hopper to the filter screen, the bottom in the box body is a slope surface, and a coarse material outlet and a coarse material pipe are arranged at the lowest position of the slope surface.
