Abstract. In the paper the choice of reasonable structure of automated system for multicomponent batching of bulk materials has been substantiated to minimize the batching error of about 3% in case the recipe mixture includes small components of big importance in terms of efficiency and cost. The algorithm of signal adaptation for weight controller of the electric drive control system of screw feeder, which takes into account the material properties changing and the "dropping column" mass.

Abstract.In the paper an automatic system for batching and mixing the components of combined feed is considered. A novel algorithm has been proposed for the batching error correction caused by mass of the material column dropping into the batching bin. The proposed algorithm has been validated in a simulation model and in an experimental facility.
