ABSTRACT:
An equipment for the continuous, pneumatic introduction of finely divided materials, in particular coal dust, into several consumption sites, in particular into the tuyeres of blast-furnaces is characterized by combining systems partly known in such manner, that a plurality of double-story vessels is preceded by a distribution system comprising a supply bin with metering conveyor scale and distribution bin. A pressure-resistant bucket-wheel distributor is mounted underneath every pressure-vessel, the buckets of said distributor is multiply subdivided transversely to the axis, and a pressure-pan provided with conveyor-gas hook-up and subdivided into mini-chambers corresponding to the bucket-wheel distributor is mounted underneath each bucket-wheel distributor, the conveyor lines to the consumption sites being connected to the pressure-pan.
