This article examines the critical issues surrounding the selection of an appropriate bag filter unit and filter fabric specifically designed for the removal of finely dispersed silty loam dust generated following the drum drying process in cement production. A comprehensive analysis of the gas flow parameters subsequent to the cyclone stage revealed that the dusty gas velocity ranges between 10–25 m/s, with a dust concentration of approximately 1640 mg/m³, an operating temperature of 145–160°C, and the predominant fraction of particles situated within the 2–10 μm range. The evaluation of various equipment designs and filtration materials was conducted based on a rigorous four-stage system analysis. Consequently, a bag filter construction featuring pulse-jet regeneration was identified as the most optimal solution for these specific industrial conditions. Comparative assessments of various fabrics demonstrated that a combined material based on glass fibre, basalt, and polyester exhibited the highest performance levels in terms of thermal stability, mechanical durability, resistance to abrasive wear, and the efficient capture of fine particulate matter.
