FIRE-GRATE TROLLEY FOR SINTERING MACHINE Russian patent published in 2007 - IPC F27B21/08 

FIELD: sintering equipment for agglomeration of ores and concentrates.

SUBSTANCE: proposed fire-grate trolley has frame with load-bearing beams of traveling rollers and stationary sides connected with detachable sides. Working surfaces of detachable side walls are closed with rectangular metal plates secured to them in zone of intersection of diagonals of plates; they are located at spaced relation for free linear expansion in each pair of plates. Plates are so distributed over surface of side wall that length L is equal to 0.1-0.25 of length of wall and height h is equal to 0.2-0.5 of height of detachable side. Thickness of plate is 1-3 of thickness of side wall. Plates project above upper edges of sides for protection of them against direct radiant heating and ignition of burden in sintering machine hearth.

EFFECT: enhanced resistance of trolley detachable sides.
