Abstract
The invention is related to a scroll conveyor tile protection or any other material subject to wear with a weldable support (41) and a wear resistant insert (6), not necessary weldable. The support (41) is fit with a flat surface and shoulder allowing for precise positioning of tile on a scroll flight (3) to be protected. At least one opening, preferably at its center, allows for insertion and assembly of a complementary shaped insert. The unit setting up on the scroll flight and the contact between the flight faces and the unit faces allows for creating a dove tail locking system. Welding of the support permanently insures locking of the system and insert being maintained without other means of fixation than this mechanical clamping.

A wear-resistant tile for attachment to a scroll flight of a rotor, comprising:
- a support part attachable to the scroll flight and defining an opening;
- and
- an insert having one portion fit within and retained only mechanically to the support part through the opening of the support part, and another portion defining a primary wear-resistant surface.
A conveying device having a rotating scroll flight with circumferentially attached wear-resistant tiles, wherein each tile comprises a support part fixed to the scroll flight and defining an opening;
- and an insert having one portion fit within and locked only mechanically to the support part through the opening of the support part, and another portion defining a primary wear-resistant surface.
