Abstract: The present disclosure relates to the sintering cycle method and apparatus of a kind of box-type sintering machine, which is peculiarly applicable to the production of lightweight aggregate using fly ash or industrial waste by sintering process. This apparatus includes four conveying systems, ignition station #1, ignition station #2, one tilt discharger, and one crusher; the box-type sintering stacking line A and B are straight and parallel, sharing one coarse dust collector; each box-type sintering stacking line is equipped with overhead workstation gantry crane rails and cranes, and each crane comprises two parts, i.e., hoist system and single rail trolley system; each box-type sintering stacking line has multiple sinter boxes; each sinter box has an air chamber below, under which there is the air chamber pipeline connected to the coarse dust collector.
