With the cooperation of the vibration assembly, the material is screened for the first time, and the large particles remain in the upper screen 5. Since the upper screen 5 is arranged in a wavy shape with convex upper part and concave lower part, the area of the material screened at a single time can be increased, thereby increasing the amount of material screened at a single time, which has the effect of improving the screening efficiency. The material passing through the upper screen 5 falls into the lower screen drum 6 and is vibrated and screened again. Since the sieve holes of the upper screen 5 and the lower screen drum 6 are inconsistent, the medium-sized particles remain in the lower screen drum 6, thereby achieving the effect of automatically screening different particle materials twice in succession.

[0028] After a certain period of crushing and screening, the staff pulls the mounting cylinder 2 out of the semicircular mounting slot of the chassis 1 through the semicircular mounting plate 3, removes the lower screen cylinder 6, and cleans and tidies up the upper screen 5 and the lower screen cylinder 6 respectively.
