A mechanical conveying device (18) for conveying binding agents from the storage container (10) into an intermediate chamber (20) is connected to the storage container (10). A pneumatic conveying device (36) for conveying the binding agent to the spreading device is connected to the intermediate chamber (20). A pressure relief device (40, 41) is connected to the mechanical conveying device in order to avoid the entry of compressed air into the storage container (10). The invention furthermore relates to a conveying system for a dry-bulk tanker and to a work train for working soils with a self-propelled ground working machine and a dry-bulk tanker. ## Claims ### Claim 1 A dry-bulk tanker for the provision of binding agent for soil stabilization to a spreading device, the dry-bulk tanker comprising: a storage container for the binding agent; at least one intermediate chamber; at least one mechanical conveyor configured to convey the binding agent from the storage container to the at least one intermediate container; a pneumatic conveyor configured to convey the binding agent from the at least one intermediate chamber to the spreading device; and a pressure relief device connected to the at least one mechanical conveyor, the pressure relief device including a vent line connected to the storage container such that overpressure in the mechanical conveyor is vented to the storage container. ### Claim 2 (depends on 1) The dry-bulk tanker of claim 1, wherein: the at least one mechanical conveyor comprises a gravity conveyor. ### Claim 3 (depends on 1) The dry-bulk tanker of claim 1, wherein: the at least one mechanical conveyor comprises a rotary feeder including a plurality of conveying chambers. ### Claim 4 (depends on 1) The dry-bulk tanker of claim 1, further comprising: a positive pressure outlet communicated with the storage container; and a filter configured to prevent binding agent from passing through the positive pressure outlet. ### Claim 5 (depends on 4) The dry-bulk tanker of claim 4, wherein: the vent line of the pressure relief device is communicated with the positive pressure outlet. ### Claim 6 (depends on 1) The dry-bulk tanker of claim 1, wherein: the pneumatic conveyor includes a compressor and a pressure line connecting the compressor to the at least one intermediate chamber. ### Claim 7 (depends on 1) The dry-bulk tanker of claim 1, wherein: the at least one mechanical conveyor includes at least two mechanical conveyors configured to convey the binding agent from the storage container to the at least one intermediate chamber. ### Claim 8 (depends on 7) The dry-bulk tanker of claim 7, wherein: the at least one intermediate chamber includes at least two intermediate chambers; and each of the at least two mechanical conveyors is connected to a separate one of the at least two intermediate chambers. ### Claim 9 (depends on 8) The dry-bulk tanker of claim 8, wherein: the at least two intermediate chambers are arranged in series with respect to the pneumatic conveyor. ### Claim 10 (depends on 1) The dry-bulk tanker of claim 1, wherein: the pneumatic conveyor includes a conveying line configured to feed the binding agent from the at least one intermediate chamber to the spreading device, and the pneumatic conveyor includes a pneumatic bypass line bypassing the at least one intermediate chamber and connected to the conveying line. ### Claim 11 A work train for working soils, the work train comprising: a self-propelled ground working machine including a milling or mixing rotor arranged in a rotor housing, and including a spreading device for spreading binding agent; and a dry-bulk tanker including: a storage container for the binding agent; at least one intermediate chamber; at least one mechanical conveyor configured to convey the binding agent from the storage container to the at least one intermediate container; a pneumatic conveyor configured to convey the binding agent from the at least one intermediate chamber to the spreading device; and a pressure relief device including a vent line communicated with the at least one mechanical conveyor and communicated with the storage container such that overpressure in the mechanical conveyor is vented to the storage container. ### Claim 12 (depends on 11) The work train of claim 11, wherein: the spreading device includes a buffer container for the binding agent; and further comprising a conveying line connecting the pneumatic conveyor to the buffer container.
