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. |
