On the other hand, they only promote themselves over short distances (e.g. a maximum of 400 m). In general, it can be stated that both the pneumatic conveyance of dry mix. And the hydromechanical conveyance of wet mix that they are large rooms, bunkers, blind shafts, for the soles, because of the fixed pipelines, less flexible fastening, for the backfilling of warping plates.
