Conveyor belt dust control.
Minneapolis, MN: U.S. Department of the Interior, Bureau of Mines, Contract H0113007, 1984 Jul; :1-410
The belt conveyor is one of the major pieces of equipment for transferrring bulk material in mining operations. However, considerable amount of respirable dust may be generated whenever the bulk material is loaded, dumped, or transferred. This report identifies and evaluates various dust control technologies applicable to belt conveyors and describes how an integrated systems approach can reduce dust emissions at a transfer point. Phase I of the program consisted of a literature search and a critical evaluation of various dust control technologies. The work established that a comprehensive approach to calculating exhaust volumes for dust collection systems does not exist. The parameters that affect the wet dust suppression efficiency were also reviewed. Based on the Phase I work, bulk material handling systems and dry dust collection or wet dust suppression systems were designed and installed at a number of transfer points in a limestone processing facility, a surface mine selected as a field test site. Field test data were used to determine the validity of various exhaust volume calculations at the different transfer points. The field test data also formed the basis for the evaluation of the relative effectiveness of commercially available and wet dust suppression systems in controlling respirable dust emissions.
