This invention discloses a pelleting device for treating snakehead skin rot in snakehead fish farming. The invention relates to the field of pelleting equipment technology and includes a composite mechanism. This pelleting device for treating snakehead skin rot in snakehead fish farming utilizes a composite mechanism design. Material enters the composite shell through the feed inlet.
