Abstract: A grate bar is provided for use in forming a grate bar assembly of a sintering pallet car. The grate bar comprises an elongate body having top surface for receiving a load, a pair of opposed arms, and a pair of opposed feet, with each arm and foot pair retaining the frame of the car therebetween. Each of a pair of peripheral spacers extends laterally away from the body to distance the body from a body of an adjacent grate bar. Each of a pair of central spacers is located between the peripheral spacers and extends laterally away from the body to distance the body from the body of the adjacent grate bar. At least one of the plane defined by a peripheral spacer top wall and the plane defined by a central spacer top wall is below the plane defined by the top surface of the elongate body.

Abstract: The present invention relates to a pressure roller bearing for a pallet car of a pelletizing machine. The bearing includes an external annular race having: an exterior surface for reversible mating engagement with a tooth gap of a wheel, a pair of sidewalls defining ends of the bearing, wherein the radial diameter of the exterior surface at a center portion in the axial direction is greater than the radial diameter of the exterior surface at the ends of the bearing, and an interior annular groove; an internal annular race defining a hole therethrough for receiving an axle, and having an exterior annular groove; and a plurality of rolling cylindrical members located in an interior space defined by the interior annular groove and the exterior annular groove when the internal annular race is received by the external annular race.

Abstract: The invention relates to a sidewall for use in a sintering pallet car. The sidewall has a base for connection to a frame of the pallet car and a wall extending upwardly from the base to a top. The wall has opposing ends, opposing interior and exterior faces, and a height as measured from the base to the top. An elongate brace is disposed on the exterior face intermediate of the opposing ends, the brace extending downwards from the top towards the base. The sidewall may include an arcuate protrusion disposed on the interior face intermediate the opposing ends of the sidewall or a cap extending between the opposing ends of the sidewall and joining the exterior and interior faces, the cap having a protruding lip extending from the exterior face. The sidewall may comprise a top segment and a bottom segment, releasably securable to each other.
