Only minimal tolerances are allowed, which, for media with difficult properties with regard to grain size, flow behavior, consistency, and bulk weight, requires precision work where design and process technology are concerned. When raw materials, aggregates etc. are added to the processing chain or when products from the process are to be filled into receptacles such as sacks, tanks etc., a wide range of challenges need to be solved. Examples of this include media that has clumped together in storage, dust formation, ensuring exact/calibrated quantities etc.
