Abstract
An apparatus includes a feed chamber for feeding of material from storage bunkers and a lifting device for lifting the material to a high level. The lifting device includes a delivery end to which a transport line for conveying the material away to a remote delivery point can be connected, a pressure vessel having a vertical conveyor that begins in the feed chamber and ends in a top region of the pressure vessel, and a discharge pipe beginning in a bottom region of the pressure vessel and leading out of the pressure vessel. The apparatus also includes a pressurizing device which pressurizes the pressure vessel via a first valve and activates a conveying air nozzle of the discharge pipe via a second valve, and a controller for filling the pressure vessel via the vertical conveyor, fluidizing the material via the pressurizing device, and conveying the material away via the transport line.
