||Chemical and particle-size analysis of dust discharged into the atmosphere by a foundry shot-blasting chamber revealed high loads of free silica (92-94%) and respirable particles of less than 5Ám (≈72%). Currently used dust collectors (cyclones) proved to be very inefficient, with outlet air dust concentrations averaging 1060mg/m3 for the iron foundry and the steel-casting department, respectively. To correct the situation, a two-stage dust control installation was designed, consisting of a cyclone and a dust capturing device with an adjustable fibrous vibration-cleaned filter packing of lavsan-type textured fibres (description and diagramme presented). Introduction of the collector at a mechanical engineering plant helped to bring outlet dust concentrations down to 10-15mg/m3 and to prevent an annual economic loss of 167,000 roubles. Filtration efficiency was 99.2-99.5% and the time between regenerations 24-25hrs.
