The invention discloses a feather screening system and method for badminton production. The feather screening system comprises a vibration plate, a light-impurity removing conveyor belt, an adsorption conveyor belt and a flat conveyor belt. The light-impurity removing conveyor belt is connected to the position below the outlet end of the vibration plate, the flat conveyor belt is connected to the position below the downstream end of the light-impurity removing conveyor belt, the adsorption conveyor belt is arranged at the perpendicular position above the flat conveyor belt, an air outlet device is arranged below an upper conveyor belt layer of the light-impurity removing conveyor belt, the air outlet device blows air towards the light-impurity removing conveyor belt, the adsorption conveyor belt is internally provided with a pumping device, and the pumping device pumps a lower conveyor belt layer of the adsorption conveyor belt. The feather screening method comprises the following steps that firstly, feathers are sequentially distributed; secondly, light sundry feathers are removed; thirdly, light-level feathers are screened out; fourthly, the light-level feathers are classified; and fifthly, heavy-level feathers are classified. By means of the feather screening system and method, the manual screening process is greatly shortened, the classification efficiency is improved, and the classification accuracy is also improved.
