An apparatus for mixing a powdery medium with a fluid includes a mixing vessel which can be filled with the fluid and which has a feed for the fluid, an inlet for the powdery medium and an outlet for the fluid mixed with the powdery medium, and at least one mixing screw arranged inside the mixing vessel and driven by a rotary drive.

Apparatus for mixing a powdery medium with a fluid

The application relates to a metering apparatus for introducing a powdery medium into a fluid, comprising a guide device for guiding the fluid and a metering device, said metering device being arranged above the guide device such that the powdery medium released by the metering unit is scattered onto the surface of the fluid.

Metering apparatus and method for introducing a powdery medium into a fluid

A metering apparatus for introducing a powdery medium into a fluid includes a mixing vessel that can be filled with a fluid and a metering unit for the powdery medium. The metering unit has an inlet for the powdery medium, an inlet for a compressed gas and an outlet extending towards the mixing vessel, through which the powdery medium and the compressed gas can be discharged into the mixing vessel.

In a method and an apparatus for replacing old underground conduits (), the old conduit () is first laid bare with the aid of a ground drilling device () with an overdrilling head and then, in turn, a new conduit () is drawn in with the aid of the drill rods () and at the same time&#x2014;in a uniform operating step&#x2014;the old conduit is pulled out of the ground.
