Abrégé

A plant for transporting loose solid material by means of a vector fluid, comprising a conveyor line (20, 3) of the material to be transported, means (4) for establishing internally of the conveyor line (20, 3) a vector fluid current, and a first dispensing device (21 ) for cyclically releasing a predetermined quantity of material to be transported at an intermediate point in the conveyor line (20, 3), wherein it comprises at least a second dispensing device (21), located in series with the first dispensing device (21 ) along the conveyor line (20, 3), which second dispensing device (21) cyclically releases a predetermined quantity of material to be transported at an intermediate point of the conveyor line (20, 3), in an alternating order with the first dispensing device (21 ).
