Abstract
A device and method for conveying bulk material, said device comprising a movable conveying member and an outer wall that is stationary in relation to the conveying member, wherein the device is connected to a further processing chamber for receiving and further processing the bulk material and a dynamic seal is used which seals with respect to the differential pressure between the further processing chamber and regions lying upstream in the process. A seal element of the dynamic seal formed of a sealant in the form of a material pattern or material seal that can be regenerated during operation of the conveying device, wherein the seal element is provided from a branch flow of the bulk material to be conveyed or from a separate sealant source.
