Abstract
The apparatus comprises stations or silos for accumulating the material, which are connected to stations for the drawing thereof through a pneumatic line including a recycling section which conveys the "trailings" or residues of material towards the silos thus performing the recovery thereof. Devices mounted on the pneumatic line at the stations perform the drawing of the material during its conveyance in the pneumatic line and discharge it therefrom, while for performing the recycling they allow the free transfer of the residues towards the silos.
