Dust Suppression. In general, any method of agglomeration improves the handling and application of a material, most notably because of the de-dusting it offers. The benefits of a granular (de-dusted) product over raw fines are many: Improved Product Performance: Product performance can be improved in a variety of ways as a result of ...

When looking to minimize fugitive dust, care should be taken to ensure the selected elevator is fully welded to prevent any points of material escape. Dust pick-off points can be added to keep a slight negative pressure inside the casing, allowing dust to be extracted and collected, while minimizing dust within the elevator casing.
