Title Dust-control equipment for points where dusty materials are transferred
Original title Ustanovka dlja obespylivanija peregruzočnyh uzlov pyljaščih materialov [in Russian]
Bibliographic information Sep. 1982, No.9, p.57-59. Illus. 4 ref.
Abstract A dust-collecting hood is described which is to be fitted over points where dusty material is dropped onto a belt conveyor. The hood is divided into 2 enclosures, one around the transfer point itself and another farther along the receiving belt. The 2nd enclosure is connected (1) to an exhaust ventilation system and (2) to the 1st enclosure via a channel containing water-spray nozzles. Tests in an ore-enrichment plant showed that the performance of the device varied with the particle size and water content of the material being moved, with the rate of movement of the conveyor, and with the rate of air flow through the hood. For a given material, conveyor speeds and air flows can be found which reduce dust levels in the vicinity of the transfer point to concentrations below the TLV.
