Dura-Life Filter Bags Performance in Cement Dust Collectors

This case study examines the performance of Dura-Life filter bags in cement plant dust collectors, specifically addressing the challenges faced by a major cement manufacturer in the United Kingdom. The document outlines the problem of short filter life, where standard polyester oleophobic bags lasted only three months due to moisture causing dust cake and nodules on the media surface. The solution presented is the Dura-Life filter bags, which provide effective filtration for nine months, significantly outperforming the standard options. The study details how the Dalamatic dust collector, installed at the head of the bucket elevator, vents the elevator casing and cement discharge point. It also notes that the Dura-Life bags operate at a lower pressure drop, enhancing the cleaning system's ability to pulse cement off the bags. The case study emphasizes the importance of evaluating product suitability based on specific application conditions, as various factors can influence performance.
