A screw conveyor (2) intended and formed for use in a decanter centrifuge for separation of solid particles from a fluid compound, comprising a central body (10), at least one conveyor thread (11a; 11b) and at least one baffle (12) bridging a flow path formed between different parts of the conveyor thread. The screw conveyor (2) has at least two originally separate parts (22, 23), each of which comprises a portion of said conveyor thread (11a; 11b) and which are kept together axially. The baffle (12) constitutes a separate member arranged to be kept in place between said parts (22, 23) of the screw conveyor, when these parts are kept together axially, and has a portion (26; 27) which forms a part of the conveyor thread (11a; 11b) in an area where the conveyor thread intersects with and extends past the baffle (12).
