A decanter centrifuge has a hollow, rotatable drum with a screw conveyor comprising a core body ( 1 ), in which an inlet opening for material into the drum from an inlet chamber ( 3 ) is provided, the inlet opening having a delimitation surface ( 7 ) which is rear relative to the direction of rotation and extending substantially axially, said delimitation surface being provided with a wear reinforcement member ( 8 ). The wear reinforcement member extends along the rear delimitation surface ( 7 ) into the inlet chamber ( 3 ). The wear reinforcement member ( 8 ) is provided with abutment surfaces ( 11; 19 ) in abutment against abutment surfaces associated with the core body, which during operation prevents the wear reinforcement member ( 8 ) from moving tangentially forwards in the in the direction of rotation and radially out of the core body ( 1 ). At least one of said abutment surfaces associated with the core body ( 1 ) is constituted by a removable blocking member ( 17 ). The wear reinforcement member ( 8 ) and the inlet opening ( 5 ) are designed in such a manner that the wear reinforcement member ( 8 ) can be introduced to its operating position from the exterior side of the core body ( 1 ) |
