The invention relates to a bellow compensator for a charging installation of a metallurgical furnace. The bellow compensator comprises an inlet end pipeand an opposite outlet end pipeand a bellow sectionarranged between the inlet end pipeand the outlet end pipe, the bellow sectionbeing formed by a series of folds and allowing relative movement between the inlet end pipeand the outlet end pipe. According to the present invention, a non-structural flexible liner, preferably wire mesh gasket, is arranged along an inner wallof the bellow compensator and extends over at least some of the length of the bellow section. The non-structural flexible linerhas a first endand a second end, wherein the first endis fixedly connected to the inlet end pipeand the second endis fixedly connected to the outlet end pipe

Bellow compensator

A distribution device for distributing bulk material with a distribution spout on a cardan suspension that has a first and a second gimbal member pivotable about two perpendicular suspension axes where a drive arrangement has a first and a second transmission mechanism for controlling pivotal motion of the distribution spout about the suspension axes, and the drive arrangement has a further cardan joint, with a first part pivotable about a third axis and a second part pivotable about a fourth axis, and a rotary motor for driving a rotary drive shaft that is connected to the cardan joint by means of an articulated connecting arm such that the rotational position and the axial position of the drive shaft determine the pivotal position of the second part about the third and fourth axes respectively, where the transmission mechanisms transmit torque about the third and fourth axes from the cardan joint to the cardan suspension for pivoting the distribution spout about the first and second axes respectively.
