Apparatus for removing dust from pyroprocessed particulate material

摘要

Apparatus for minimizing dust in a kiln system for pyroprocessed particulate material such as lime received from a source such as a kiln. A suction nozzle is located in close proximity to the underside of a stream of falling particles discharging from a kiln where fines are noted to be characteristically concentrated and another suction nozzle is located under an underlying grate immediately adjacent the stream of falling particles channeled through the grate and in the zone of highest concentration of fines. By thus locating the nozzles in the zones of maximum concentration of fines significant quantities of dust can be removed by utilizing only a small fraction of the air and power required with other dust removal systems.
