This thesis deals with the construction of a dispersing apparatus into an electric furnace. First, a simplified flow chart was created to divide the process into individual units. Subsequently, the individual components which are necessary for the respective sections are being discussed in the state of the art research. From the acquired knowledge of the advantages and disadvantages and by considering the given boundary conditions, the suitable aggregates were selected, combined and finally designed. Depending on the requirements, analytical and experimental investigations as well as a CFD simulation were used. At the end, the functionality of the system was proven by successful commissioning. The first part of the process is the storage unit, which was integrated into the existing system, but taking into account that due to the fineness of the feed material, different mechanical behavior when discharging may occur. To prevent clogging, it is necessary to install mechanical or pneumatic discharge aids. A volumetric double-concave screw device was chosen as a dosing unit, because it’s known to be particularly suitable for bulk materials which are difficult to handle. It showed that there is a very good linear relationship between speed and flow, which eases the controllability of the whole process. Due to the thermal and abrasive conditions in the dispersing unit, no system with moving parts should be used. Therefore, a static solid/gas-injector was selected. It could be shown that this worked reliably in the laboratory tests as well as in the commissioning phase. The conjunction from the dispersing unit into the furnaces was realized by means of a multiple diffuser. The problems occurring during the testing phase in the form of instable flow conditions could be solved by means of a CFD simulation. An AMCA flow rectifier was installed to homogenize and parallelize the flow.
