Abstract

The disclosure relates to a machine for thermal treatment of bulk material, comprising: a stationary furnace which presents a support structure, and a plurality of pallet cars traveling through the furnace, said plurality of pallet cars together defining, at a lateral side thereof, a common engagement surface which extends through the furnace, wherein a gap is defined between the support structure of the furnace and the common engagement surface, said gap having a gap length, the machine further comprising: a sealing system comprising a series of leaf members which are partially overlapping, wherein each leaf member of the series of leaf members is connected to the support structure at a first end thereof, and self-biased into engagement with the engagement surface at a second, opposite, end thereof such that the series of leaf members, together, cover the gap over at least part of the gap length.

Description

technical field [0001] The invention relates to a machine for heat treatment of bulk materials. More specifically, the present disclosure also relates to a sealing system for use in a machine for thermally treating bulk material. Background technique [0002] Machines for heat treatment of bulk materials, such as sintering or pelletizing (pelletizing) systems, are known in the art. These machines are configured to convert bulk material or pelletized concentrate (granulated concentrate) into hardened pellets (hardened pellets), which can be used, for example, as blast furnace feed ) or direct reduction furnace feed. These machines include a furnace and a plurality of pallet trucks arranged for conveying bulk material into the furnace. The machines include different heating and cooling zones and the pallet trucks are arranged to transport the bulk material through the different zones of the machine to produce hardened pellets. [0003] The problem with these machines is th...
