A method of installing tiles via interposed tile carriers on a scroll of a centrifuge comprises mounting each tile carrier (11) prior to a welding step in the required position on a centrifuge flight by means of an individual tile clamp (32), with mechanical inter-engagement between each carrier (11) and its clamp (32), thus positioning each carrier (11) in the same position relative to its clamp (32) on each application, the tile clamps (32) being of a set width, so that when mounted side by side they pitch the carriers (11) so that when the tiles (10) are inserted there are no gaps between the tiles, thus giving a smooth surface without having to dress the tiles. Mounting is followed by welding the carriers (11), whilst held in position by the tile clamps to the centrifuge flight. The tile clamps; are then removed and once the tile carriers have cooled down to ambient temperature the tiles (10) are inserted and secured to their respective carriers (11). The invention also includes a method of inserting a dovetail ribbed tile (10) into a dovetail grooved carrier (11), and also a certrifuge flight (31) or scroll incorporating such tiles and carriers, and also a centrifuge incorporating such a scroll.
