  • Patent number: 9546047
    Abstract: The present disclosure relates to a slat conveyor for transporting material in mining and extraction systems. The slat conveyor may comprise a plurality of channel elements arranged in a series, a material-transport strand and an oppositely-moving return strand. The slat conveyor may further comprise an endless conveyor including a conveyor chain and a plurality of transport plates with a plate section, which may be pivotable downward in a delivery area for the transported material. Thus, for example, a flat-constructed slat conveyor (apron conveyor) having a low loading height may be provided.
