The present invention relates to a metal dust collecting apparatus. More specifically, the metal dust collecting apparatus can increase the metal dust collection efficiency while not using water. The metal dust collecting apparatus does not use the water to minimize the water pollution and the economic burden of installing and maintaining a water treatment facility. The metal dust collecting apparatus circulates the high-temperature compression air drawn in through a duct instead of discharging the air to the outside to minimize the amount of the metal dust being discharged to the atmosphere. When the compression air is circulated in the duct, the temperature of the compression air drops by a predetermined degree to minimize the likelihood of failure of a compression air spraying unit due to the high temperature compression air. |
