Abstract
The invention relates to a device for the pneumatic conveyance of bulk material, including a conveying pipe which defines a conveying path for the bulk material and in portions has a fluidizing pipe segment and a propellant gas source which is connected to the conveying pipe and is designed for the supply of propellant gas in the direction of the conveying path. The conveying pipe is provided with a fluidizing pipe segment at least in the region of a bulk material feed means and, if appropriate, also at further critical portions of the conveying pipe, in particular upstream of deflection points. As a result, the bulk material, which is often encountered there in a high concentration, can be fluidized, with the result that it can be conveyed, with low friction, at relatively low gas velocities. The invention relates, furthermore, to a corresponding conveying method.
