In this study, a study on the design of the rake shape of a rotary screener is conducted. The rake bar and rake of a rotary screener were designed, and three types for the rake shape were designed by changing the rake shape. Structural analysis was conducted in consideration of the vertical load applied when the narrow object was pulled up by the rake and the friction force applied underwater, and the more efficient type was verified by comparing the stress and strain applied to the lake by shape. In addition, structural analysis was additionally performed by changing the material of the rake to a carbon composite material in the same manner. That is, in order to improve the need to replace the entire rake part in case of damage, we will examine the improvement of the strength of the rake by performing structural analysis by changing the material of the rake.
