The invention discloses a rapid judgment device for needle-sheet-shaped particles of coarse aggregate. The device comprises a base, a first vibration motor is installed at the top of the base, an installation plate is arranged at the top of the first vibration motor, a first rotating motor is installed at the top of the installation plate, and the top of the first rotating motor is in transmissionconnection with a rotating shaft through a speed reducer. By means of a spiral track, coarse aggregate can be vibrated upwards while rotating backwards, so that the coarse aggregate with different lengths passes through the first through holes with the corresponding lengths and falls into the corresponding collecting boxes, and then the lengths of the coarse aggregate are distinguished; the device box can enable coarse aggregate with the diameter smaller than that of the second through hole to pass through the supporting plate, then the thickness of the coarse aggregate is sorted, the two modes are combined, the devi
