Wherein the height of the gap of the screening channel 33 is the vertical distance between the bottom of the screening and the top surface of the support table 51.
The material screening wheel 3 is connected to the material screening wheel driving device to drive the material screening wheel 3 to rotate through the material screening wheel driving device, and the rotation center line of the material screening wheel 3 is horizontally arranged and is parallel to the preset first direction X. In this embodiment, the first direction X and the second direction Y are horizontal directions, and the two directions are perpendicular to each other. The outlet 542 of the feed channel 54 and the screening wheel 3 are arranged in succession along the first direction X. Above the top surface of the support table 51, the discharge hole 542 and the sieve channel 33 communicate to form a passage.
