  • Patent number: 4609309
    Abstract: A process for the transport of powdered or particulate material from a container, such as a tank of a ship, via its upper opening to a separately disposed delivery location. The transport occurs with a transport apparatus which is provided with a feed head (31) for the detachment and feeding of material to the transport apparatus at its material intake end. The feed head pushes the material laterally inwards into the lower end of an upwardly directed transport pipe (30) just above an upwardly directd air current for fluidizing of the material gradually as it is pushed into the transport pipe and for transport of the material in the height direction through the transport pipe in a fluidized condition. The feed head is preferably provided with two diameterially opposite material feed openings for pushing the material from opposite directions towards the central axis of the transport pipe.
