Cement industry

CO2 savings have been one of the central themes of recent years in energy-intensive industries. The use of alternative fuels plays an increasingly important role in the cement industry in particular. At STELA we offer the tailor-made modern solution through drying systems: the drying of RDF (Refuse Derived Fuel) & SSW (solid shredded waste) ensures controllability and quality assurance in clinker production. Since our dryers also use the waste heat from upstream production processes, the economic operation of the drying system is also ensured.

Belt dryer type BT with air circulation

If products require drying to a very low final moisture content, the problem usually arises with traditional drying systems that the air has a lower saturation point towards the end of the drying phase. At the same time, there is still a large amount of heat that could be used in the exhaust air, which is released into the surrounding area.
