Abstract: A device for cooling the supporting trunnions of a distribution spout of a charging installation of a shaft furnace, wherein the spout is mounted pivotably about a horizontal axis on a shell coaxial with the furnace and the spout is attached rotatably to the trunnions driven in rotation by a drive component. The trunnions are directly attached for rotation by their ends to output shafts of reduction gears and include internal cooling channels. The cooling device includes feed and return ducts for the cooling water circulating in the internal channels. The feed and return ducts are connected to the trunnions by connectors fixed to the cylindrical surface of the trunnions. The feed and return ducts are arranged to permit rotational displacement of the connectors about the pivot axis of the spout during pivoting of the spout, in particular by passing through oblong slots extending circumferentially in the wall of bearings supporting the driving reduction gears.

Abstract: A simple and compact device for wet granulation of liquid slag, comprising a granulating basin with a water injection device and a decanting basin that is separate from the granulating basin. A distribution channel for the granulate-water mixture extends above the decanting basin and is provided with outflow means along the entire length and on the lower side thereof for the granulate-water mixture. A vertical inflow shaft that is open towards the bottom is arranged underneath the distribution channel. The outflow means for the granulate-water mixture discharges into said inflow shaft.
