  • APPARATUS FOR DISCHARGING BULK MATERIAL
    Publication number: 20130202368
    Abstract: An apparatus for discharging bulk material from a container containing gas includes a single-shaft screw conveyor including a conveying tube having an axis of symmetry. A purge tank is disposed downstream of the screw conveyor with the conveying tube opening into the purge tank. The purge tank includes ports for a supply and discharge of a purge gas stream and an outlet opening for the bulk material. A closing cone with a cone tip and an axis of symmetry is shiftably mounted on its axis of symmetry. The closing cone is pressed with the cone tip from outside into an outlet opening of the conveying tube. The axis of symmetry of the closing cone coincides with the axis of symmetry of the conveying tube.

  • Method for continuously producing melamine
    Patent number: 8431696
    Abstract: A process for the continuous production of melamine from urea by means of a fluidized-bed reactor, wherein process gas guided in the process circuit is used as fluidizing gas and wherein the temperature of the process gas at the inlet of the conveying means for the fluidizing gas is adjusted by adjusting the mixing ratio of a process gas stream guided over a scrubber and of a process gas stream guided past the scrubber.
