Abstract
A method for conveying material by applying a pressure difference in a conveying conduit (), in which method the material is fed into the conveying conduit () and in the conveying conduit further into a separating device (), where the material being conveyed is separated from conveying air, in which method a negative pressure is created in the conveying conduit () by means of an ejector apparatus (), whose suction side is connected to the separating device (), said ejector apparatus being operated using an operating medium consisting of a liquid mist, especially an aqueous liquid mist, said medium being sprayed through at least one spraying nozzle () into an ejector tube () directed into a separating element (). In the method, the generation of the negative pressure to be produced is intensified according to need by limiting the flow of gases, such as air, into the ejector tube () from the direction opposite to the spraying direction of its operating medium, i.e. from the outlet end () of the ejector tube. The invention also relates to an apparatus and an ejector device.
