Screening device for ceramsites with different particle sizes

The utility model relates to a screening device for ceramsites with different particle sizes. Including a machine frame, wherein a rotary screen is rotatably connected to the rack, a plurality of groups of screen holes are formed in the outer circumferential surface of the rotary screen in the length direction, a plurality of collecting boxes corresponding to the screen holes are arranged below the rotary screen, side baffles are arranged on the rack and located on the two sides of the rotary screen, the side baffles are vertically arranged, the bottoms of the side baffles are connected with the tops of the collecting boxes, and buffer components are arranged on the inner surfaces. During working, ceramsite enters the rotary screen from the feeding hole; sieve pores with different diameters are formed; the ceramsite with the corresponding diameter can be screened out; lower part of rotary screen, sieve holes with different hole diameters, corresponding collecting box, ceramsite with the same grade diameter is
