PURPOSE: A centrifugal having a structure-improved screw conveyor, and a manufacturing method of a screw conveyor are provided to facilitate the production thereof. CONSTITUTION: A centrifugal having a structure-improved screw conveyor comprises: a driving means(100); an external drum(200) and a internal drum(300) rotated by receiving driving power from the driving means; and a screw conveyor(400) installed on outer circumference to be arranged between the internal drum and the external drum. In the internal drum, a plurality of uneven mounting parts(340) screw-arranged with constant gaps on circumference side. The screw conveyor comprises: mounting parts(411) corresponding with the uneven mounting parts; medium bodies(412) connected to the same; uneven insertion part(413) on circumference separated from the outer circumference of the internal drum, connected to the medium bodies; a plurality of medium members(410) fix-installed to each mounting parts, and spiral wing part(420) consisting of two or more segments, forming a space part separated from the internal drum by being insert-fixed to each medium members with the shape connecting the medium members. |
